 note = {Fluoride glass containing rare earth ion radiates ultraviolet light after the absorption of red light through the upconversion mechanism. The rare-earth-ion-doped fluoride glasses were studied on the developments of their optical characteristics to apply them to the light sours for photocatalyst. Mixing several rare earth ions suggested the possibility of enhancement of the upconversion emission. 350-nm light was detected from the Tm^<3+>-doped fluoride glass by means of simultaneous irradiation of both 658 nm and 480 nm lights. The evaporated Ag film on the fluoride glass slightly affected the upconversion emission.},
