摘    要：考察了PBO-Bi₂O₃-B₂O₃系统玻璃的制备、组成与密度的关系及其荧光性能.研究表明,当B₂O₃引入量的摩尔分数为5%～60%时,可获得密度值为5～8G/CM³的玻璃,玻璃的密度随B₂O₃引入量的增加而减少,发射光谱证实,PBO-Bi₂O₃-B₂O₃玻璃能在可见光区发射荧光,发光原因是玻璃中含有PB^2＋,Bi^3＋发光离子,其荧光波长与玻璃组成、结构及激发波长大小有关.

Abstract: The preparation of PbO-Bi₂O₃-B₂O₃ system glasses,the relationship between composi-tion and density, and the luminous property have been studied.It is found that the transpar-ent glasses with densities 5～8g/cm³ can be gained when the amount of addition of B₂O₃ iscontrolled from 5%～60%(mole fraction).The densities of the system glasses decreasewith the increase of B₂O₃ contents,The emission spectra show that the luminescence can beemitted in the visible region,which resulted from PB^2＋,Bi^3＋contained in the PbO-Bi₂O₃-B₂O₃ glasses.The maxima emission wavelength position of the fluorescence depends on the com-position,structure of the system glasses,and excitation wavelength.
