- Abstract
- Eu3+ activated trigadolinium gallate, Gd3GaO6:Eu, was successfully synthesized using various aqueous solutions via ultrasonic spray pyrolysis. The corresponding phosphors illuminated an efficient red emission under Hg-discharge condition with enhanced color purity. which is related to prominent peaks centered at 615 and 629 nm induced by the electric dipole transition of D-5(0) -> F-7(2) of Eu3+. By using a proper Ga source for aqueous solution, especially gallium sulfate, uniformly distributed Gd3GaO6:Eu3+ phosphor with controlled morphology and enhanced emission efficiency was obtained.
