ツリウムドープフッ化物ガラスからのアップコンバージョン光を応用する光触媒反応研究用システムの検討とモデル実験 CONSTRUCTION OF RESEARCH SYSTEMS FOR PHOTOCATALYST REACTION BY APPLYING UPCONVERSION LIGHT FROM THULIUM DOPED FLUORIDE GLASS AND MODEL EXPERIMENTS

Fluoride glass containing Thulium radiates ultraviolet light after the absorption of red light through the upconversion mechanism. Incidence red light can make possible photocatalyst reactions by using these Tm-doped fluoride glasses. The research systems for the photocatalyst reaction experiments were constructed followed by their discussion of some experimental factors, and model experiments were carried out with them. About 5-7% decreases were observed in quantity of the model substances taken up after 1-3 hours irradiations. Photocatalyst reactions were demonstrated with the incidence red light by using Tm-doped fluoride glass.
