Abstract

An intense bluish-green phosphor, CaLaGa3S6O:Ce3+,Tb3+, is developed. The photoluminescence excitation and emission spectra, the lifetime, and the concentration effect are investigated. The results show that an efficient nonradiative energy transfer from Ce3+ to Tb3+ occurs and its efficiency is about 11%. Although the efficiency is not high enough, these results demonstrate that a Tb3+ ion with low 4f4f absorption efficiency in the near-UV [(n)-UV] region can play the role of activator in a narrow green-emitting phosphor. This is potentially useful in (n)-UV (380420nm) GaN-based LEDs through efficient energy feeding by allowing 4f5d absorption of Ce3+ with high oscillator strength.
