Phosphor Development and Integration for Near-UV LED Solid State Lighting

Abstract

Using the proper synthesis technique is an important consideration in the development of phosphors for white light emission from near UV LEDs (emission in the range 380 nm – 410 nm). In this review, synthesis methods are analyzed and compared, with the goal of obtaining the optimal particle size, morphology and purity. Post-synthesis treatments such as the fabrication of core/shell particles as well as annealing conditions are discussed. Finally, methods to incorporate phosphors with the diode are discussed, with an emphasis on electrophoretic deposition.
