The glasses with the composition of y(LiPO3):y[Al(PO3)]:y(AgNO3)=x:(100-x):4(x=90,80,70,60,50 in molar ratio) were prepared with conventional melt-quenching method. Effects of Al(PO3)3 contents on the physico-chemical characteristics and spectroscopic properties were studied. It is found that the refractive index,density,glass transition temperature (Tg) and onset crystallization temperature (Tx) increased with the increase of Al (PO3)3 content. The increase of aluminum content strengthens the glass network,thus improving the physical and chemical properties of the glass. The glass with the composition y(LiPO3):y[Al(PO3)3]:y(AgNO3)=70:30:4 possesses good UV transmittance,higher irradiation induced absorption,intense fluorescence intensity and lower predose. Evaluated from the physical,chemical and spectroscopic properties,y(LiPO3):y[Al(PO3)3]:y(AgNO3)=70:30:4 glass is a promising candidate material for radio-photolumi nescence glass.
