概要
- 論文の詳細を見る
The optical absorption spectrum (2 eV - 6.8 eV), the Ce" emission spectrum (1.8eV - 2.7 eV) and the excitation spectrum for the 550 nm Ce" emission (2.4 eV - 6.3eV) have been measured on single crystals of YAG:Ce". The excitation spectrum forthe 550nm emission (2.7eV -11.2eV) is also reported on powder phosphor ofYAG:Ce". With the use of these data, the energy position of all the five d lines of theCe" centre, including the highest energy component of the de which has not beenfound hitherto, could be determeined. The crystalline field splitting, IODq, of the dlevels of the Ce" centre is thereby estimated as 2.22 eV. Further, the energy locationof the lowest energy component of dy after the relaxation has been estimated.
