| Abstract: | The earlier experimental results showed that the luminescent characteristics of Tb3+ ion depend on Tb3+ ion concentration and crystal hosts.In this paper theoretical investigation of Tb3+ luminescent characteritics in pentaphosphate and mixing pentaphosphate single crystals (TbP5O14 and TbxY1-xP5O14) has been carried out. By using the Judd-Ofelt theory and absorption spectra,the parameters of the oscillator strengh were first obtained in TbP5O15crystals,resulting in O2=2.13×10-20cm2,O4=3.76×10-20 cm2,O6=2.98×10-20cm2.The probabilities of electric dipole and magnetic dipole radiative transition from 5D3 and 5D4 to 7FJ were calculated. The lifetime of electron in5D4 obtained is 4.4ms,which agrees with experimental value. |
