アップコンバージョン発光の光触媒用光源への応用のための金属微粒子が発光に及ぼす効果に関する基礎的研究  [in Japanese] FUNDAMENTAL RESEARCH ON EFFECTS OF METAL PARTICLES ON LUMINESCENCE TO APPLY UPCONVERSION LUMINESCENCE TO LIGHT SOURS FOR PHOTOCATALYST  [in Japanese]

Fluoride glass containing Thulium radiates ultraviolet light after the absorption of red light through the upconversion mechanism. Upconversion luminescence from Tm-doped-fluoride glass can be used as the light sours for photocatalyst reactions, for which the upconversion luminescence is desired to be as strong as possible. Metal particles can have some effect on enhancement of luminescence from atom and molecules. The upconversion luminescence from Tm^<3+> in fluoride glass and fluorescence from EuCl_3 in solid state were studied on the effect of metal particles on these luminescence properties. On exsistence of metal particles, the fluorescence from EuCl_3 became stronger in intensity, and the upconversion luminescence from Tm^<3+> decreased, which was due to the reflection of the incident light by the metal particles.
