Infrared visible wavelength upper part conversion material

摘要

PURPOSE: To obtain a material for changing the wavelength of IR or visible rays upward not requiring preliminary excitation, having higher changing efficiency and enhanced sensitivity to IR having 1.5μm, 0.98μm or 0.8μm band wavelength as compared with a conventional material and applicable to an IR detecting element, a laser display, etc. ;CONSTITUTION: This material for changing the wavelength of IR or visible rays upward is made of an inorg. material contg. at least erbium fluoride (ErF₃), yttrium fluoride (YF₃), barium fluoride (BaF₂) and zinc fluoride (ZnF₂) as essential components.;COPYRIGHT: (C)1994,JPO&Japio
