Study On Preparation And Properties Of Antimony Phosphate Glass Doped With Rare Earth

The glasses in xSb2O3-(70-x) P2O5-30ZnO (x=0～40mol)and xSb2O3-(65-x)ZnO-35P2O5(x=0～40mol) system were fabricated by melt quenching method and theglass-forming regions were investigated．Changing the content of components in the glasssample, determine the change trend of performance of the glasses in ZnO-Sb2O3-P2O5system,and then make sure the glass-forming regions. Looking for a set as a basic component fromthe region, Doped with rare earth Sm2O3, study the luminescence performance.The properties of the ZnO-Sb2O3-P2O5glasses were investigated by using horizontaldilatometer and infrared spectra (IR) and XRD. Determine the crystallization properties andcharacteristics temperature by DTA and thermal expansion; Analysis the performance of thesystem of glass by the test with density and resistance to acid. Results are as follows: theglass-forming region of ZnO-Sb2O3-P2O5system is larger. When the content of P2O5incomposition is too high, the stability of the glass is poor. When replacing P2O5or ZnO withSb2O3, the glass stability increased. Because some Sb2O3as a form of body, participate in thenetwork, strengthen the network, make glass structure more closely. Addition Sb2O3, open theP—P—O bond and forming P—O—Sb bond, bond strength was improved. Thereforeimprove the mole fraction of Sb2O3can significantly improve the stability of theZnO-Sb2O3-P2O5glasses system.Add Sb2O3in the ZnO-P2O5glasses system, phosphorus antimony class phase is found,that formed the P—O—Sb bound.On the basis of above research, the article studied the structure and the luminescentproperties of Sb2O3doped glass. Analyzed and tested the properties of the glass by usingemission spectrum and excitation spectrum technological. Results are as follows: Sm2O3doping amount is0.5%(mole fraction) of the luminous intensity of the glass sample is betterthan1%. Fluorescence spectrum of the test results shows that this glass system can convertthe sun’s ultraviolet light to red. To enhance the sun red light emission intensity, meets therequirements of material for turning the light.
