Challenging and development of phosphors for lighting applications

Abstract

Phosphors (inorganics luminescent material) have been extensively investigated due to their potential application especially for lighting. This article briefly reviews the developments of the phosphors for lighting application. Research and development of phosphors for the application of energy-saving lamps have been developed in the Laboratory of Instrumentation System and Functional Materials Processing, Department of Physics, Universitas Padjadjaran. To fulfill the desired feature for lighting application, we developed host-center type phosphor with compositional modifications prepared by spray pyrolysis and simple solution routes. In order to meet the industry requirement with high production rate, currently we scaled up the spray pyrolysis utilized with a pulse combustion reactor.
