The present invention provides an organic/inorganic composite containing a rare earth metal or/and Period IV transition metal in which the aforementioned rare earth metal or/and Period IV transition metal is doped at a high concentration, and control of quenching and optical transparency are assured thereby; and an optical amplifier, a light control optical element, and luminescent device utilizing the same. The organic/inorganic composite containing a rare earth metal or/and Period IV transition metal is one in which at least one species of rare earth metal or/and Period IV transition metal is dispersed in an organic polymer, with the aforementioned composite containing an optically transparent organic polymer and an inorganic dispersion phase comprising: (1) a rare earth metal and (2) another element coordinated thereto via an oxygen atom(s).
An organic/inorganic composite comprising an inorganic dispersion phase dispersed in an organic polymer, the inorganic dispersion phase comprising one or more metal atoms that are coordinated to at least one rare earth metal atom or/and Period IV transition metal atom via an —O(R)— moiety wherein R comprises an alkyl group, reactive vinyl group, aryl group, diazo group, nitro group, cinnamoyl group, acryloyl group, imide group, epoxy group, cyano group, or an alkyl group, alkyl silyl group, or alkyl carbonyl group.
A method of making an organic/inorganic composite, comprising:
