ULTRAVIOLET RAY BLOCKING MATERIAL, VISIBLE LIGHT SELECTIVE TRANSMISSION FILTER, VISIBLE LIGHT SELECTIVE TRANSMISSION RESIN MATERIAL AND LIGHT SOURCE |
| 摘要 |
PROBLEM TO BE SOLVED: To improve ultraviolet ray blocking capability at low cost and also reduce the cost for the blocking, by shifting the wavelength for ultraviolet ray blocking to a longer side than that of ZnO. SOLUTION: The ultraviolet ray blocking material is characterized in that it is mainly composed of a mixed oxides of monoclinic crystals of Bi<SB>2</SB>O<SB>3</SB>and cubical crystals of CeO<SB>2</SB>at a ratio of 12-6:1.
