1 INTRODUCTION
Materials science is an interdisciplinary field involving the properties of matter It is interested in electrical materials, electronic materials, nanomaterials, optical fiber materials The devices used for measuring fabrication are: Micro-Raman oscillator, infrared absorption spectrum, absorption spectrum, fluorescence emission spectrum The results allow for studying the lattice structure, basal energy levels and the energy levels in the ground state and the corresponding excited states of rare-earth ions
During the implementation of scientific projects, researchers must process these empirical datas; and, show them through diagrams to determine the structure and characteristic properties of the material There are many softwares available in researching and teaching such as Origin, Matlab, Excel These software can process the statistical datas, show the empirical results by diagram, extract the report of analysis results
Trang 2Matlab is a program for complex computation and result display, which is controlled
by programmed scripts Variables created inside a function are only in the workspace of that function and are released when the one terminates so it is not possible to use the information of the previous time for the next time
Excel is one of the most popular software for analyzing statistical data, analyzing results, calculating quantities according to formulas, demonstrating diagram results The disadvantage of Excel is that in each calculation, it is necessary to write mathematical formulas and data expressions that are limited to fonts when used for large units and the number of drawings is difficult to modify
Origin software has spreadsheets like Excel so you can import data from Excel or Word tables by copy, paste; or you can import the digital data files of the measurement system with the Import command This software has the advantage that after importing data and selecting the quantities to be calculated, the software will automatically output the specified statistics, whereas if using Matlab or Excel we must write or program the calculational functions
Application of Origin software to process the datas of aluminosilicate glass samples
2 RESEARCH METHODS
2.1 The Nexus 670 FT-IR infrared spectrophotometer [1]
Figure 1.
Figure 1 Diagram principle infrared spectrometry system Fourier transform
Fourier Transformation Infrared Spectrophotometer (FTIR), a fixed mirror, a moving mirror and a beam diffuser Infrared radiation passes out of the interferometer and passes
Trang 3through the detector The detector records the variation in the intensity of the radiation in the direction d that the moving mirror performs and then converts it into an electrical signal It receives the signal as a function of the voltage V in the distance, This is a
The intensity of the radiation depends on the number of waves Because of computer use, the spectra are highly automated
2.2 Processed data from the Nexus 670 FT-IR Infrared Spectrophotometer with Origin
Origin is a powerful and full featured data analysis software Powerful visualization tools with accompanying descriptive statistics to assist with hypothesis testing, model development and modeling, and data analysis [5]
The main interface of Origin is the Menus bar, toolbars, active windows such as tables, graphs
Figure 2 Figure 2 The main interface of Origin
The Origin menu provides commands to perform operations during data processing In each submenu, the tags also change to correspond to each specific window: Analysis for the Worksheet window or Analysis for the Graph window
The worksheet viewer uses data organizers and provides tools for using, analyzing, analyzing, and graphing data from worksheet data The columns in the worksheet are relative to each other by the axis specified as the X axis, the Y axis, and their location
Trang 4The Graph window is where the graphs are displayed and edited Each graph window contains a single edit page You can annotate different objects such as axes, annotations, and drawing data
Graphs in the Origin software include 2D graphs and some 3D graphs To create a graph we perform the following operations: select the file containing the data; select the data on the worksheet, in the menu bar appears Plot tab; Select Plot and choose plot style
or Click on a graphic type icon on the drawing toolbar
Origin handles data from the measurement system through the following steps:

3 RESULTS AND DISCUSSION
3.1 Processing manipulation on the Nexus 670 FT-IR infrared spectrophotometer
The sample was smoothed and blended well with KBr in powdered state 10-100 times,
transparent and the powders studied were dispersed evenly
Infrared Spectrum Analyzer is used under the brand name Nexus 670 FT-IR, manufactured by Nicolet (USA), located at the Institute of Tropical Technology of the Vietnam Academy of Science and Technology The working spectrum of the device is

Structural information was determined by the vibrating of the formed links contained
Peaks of 469 cm-1, 805 cm-1, 1106 cm-1 are thought to be vibrating of the Si-O-Si
absorbed form These observations are similar to those published in the literature [3, 4]
In addition, it can be seen that in these samples, the OH- group remains, as their

Trang 7In Figure 6, the spectrum bands are similar to Figure 4 and Figure 5 These two
peak of 907 cm-1 is attributable to the oscillation of the Si-O-Al or Si-O- groups Strips
increase in Al2O3 content
The infrared absorption spectra of samples with different composition concentrations were similar The vertices characteristic for silica glass and multi-component glass are
OH groups in the samples Infrared absorption spectra of the samples gave consistent results for the works of some authors [2,3,4]
4 CONCLUSION
Efficient application of Origin software to demonstrate the infrared spectrum diagram The characteris spectral peaks of silica glass and multi-component one
(FTIR) results show about: the information of the background of the glass network; the
linking vibration of Si-O-Al; and vibration of the groups such as Si-OH group Si-O-Er,
Al-O-Si-O, Al-O, along with the existence of the OH groups in the sample
These results may be necessary in the manufacture of silica glass and multi-component one with the high concentrations of the rare-earth ions doped, to apply the spectral properties in optical communication with the most effective way
