Research Abstract

Room temperature fabrication for the oxide phosphors (especially vanadates) has been developed by means of ultra-violet (UV) irradiation. By using UV lamp, the irradiation at vacuum ultraviolet wavelength in air was effective on the crystallization. In the UV laser irradiation process, various kinds of phosphors have been successfully crystallized by using precursor nano-particles as crystal nuclei. These new processes for room temperature phosphor film fabrication are expected to develop next generation flexible displays.
