Abstract

An intense bluish-green phosphor, Ca La Ga 3 S 6 O : Ce 3 + , Tb 3 + , 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 Ce 3 + to Tb 3 + occurs and its efficiency is about 11%. Although the efficiency is not high enough, these results demonstrate that a Tb 3 + ion with low 4 f 4 f 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 ( 380 420 nm ) GaN-based LEDs through efficient energy feeding by allowing 4 f 5 d absorption of Ce 3 + with high oscillator strength.
