The complex for phototransformation, the luminous device and the color tone control manner null which use

摘要

It can obtain necessary fluorescence with a thinner thickness, low at cost and the mixture for phototransformation which held down the loss of light with compound internal it offers. At least, the mixture for phototransformation which features that it is the mixture for phototransformation, which consists of the plural oxide phases which include the oxide crystal phase which gives out one fluorescence at least surface roughness of one surface of the luminous radiation aspect of opposite side to the optical entrance place of the mixture for the said phototransformation, arithmetic mean roughness (Ra) with it is 0.05 millimicrons or more. It is desirable, as for the mixture for phototransformation, at least the oxide phase of two or more continually and three has the organization which interwinds dimensionally mutually, among the said oxide phases at least one consists of the solidification body which is the crystal phase which gives out fluorescence.
