Preparation of transparent inorganic-organic composite phosphors incorporated with europium (III) complexes

Transparent organically modified silicates (ORMOSIL) glass phosphors with h igh emission intensity (similar to 60% vs. Y(P,V)O-4 :Eu) were prepared by incorporating with [Eu(phen)(2)]Cl-3 under optimized conditions for the ORM OSIL composition and complex concentration, and their emission intensity va riety was characterized by the (D0-7F2)-D-5 to (D0-7F1)-D-5 emission intens ity ratio. Waveguide-type sunlight collector panels made of quartz plates c oated with the ORMOSIL glass phosphor film showed an apparent enhancement f or the photovoltaic output of silicon solar cells by its fluorescence wavel ength shifting effect.
