Intense Red Phosphor for White LEDs Based on Blue GaN LEDs
Source abstract
Abstract
A series of novel red-emitting phosphors have been synthesized and their luminescence properties investigated. All activated compositions show red emission on excitation either in the charge-transfer band or levels. All compositions show remarkably intense red emission with excitation at . The photoluminescence studies on and ( in steps of 0.1) show that the emission intensity is maximum for compositions with and 0.3, respectively, and a decrease in emission intensity is observed for compositions with higher values. Select compositions in this system of compounds could find potential application as red phosphors for white-light generation using blue GaN-based light-emitting diodes (LEDs).
