Spectroscopic analysis of Eu doped silica-titania-polydimethylsiloxane hybrid ORMOSILs.

Eu doped silica-titania-polydimethylsiloxane hybrid ORMOSILs were synthesized a non-hydrolytic sol-gel route. The structural and thermal analyses of the samples confirmed that the matrix structure remains unaffected by doping with different concentrations of Eu ions. Photoluminescence (PL) studies performed at 394 nm on Eu doped ORMOSILs imply that they emit broad blue host emission and the characteristic Eu red emissions simultaneously.
