Research Abstract

The purpose of this study is to realize the potential of hexagonal boron nitride(hBN) crystal as a deep ultraviolet light emission materials. High purity single crystals of hBN were obtained under high pressure flux growth process and their optical properties were characterized. Synthesis technique of high purity hBN under atmospheric pressure was also established by using Ni base solvent system. The plot-type of deep ultraviolet emission device combined with hBN crystals and electron emitter were fabricated and its usefulness for sterilization of bacteria was realized.
