Abstract
|
|
|
|
The fluorescence of Eu3+, Tb3+ substituted for La3+ in Lanthanum Oxychloride (LaOCl) has been studied. The fluorescence intensity of the Eu3+, Tb3+ in LaOCl excited by Ultra-violet light were investigated on its activator concentration and discussed as the energy transfer process. The energy transfer from Tb3+ to Eu3+ take place in the Eu3+ and Tb3+ codoped LaOCl crystal. This process was confirmed to the change of concentration and the measurement of fluorescence decay time.
