Spectroscopic analysis of Eu³⁺ doped silica-titania-polydimethylsiloxane hybrid ORMOSILs.

ABSTRACT: Eu³⁺ doped silica-titania-polydimethylsiloxane hybrid ORMOSILs were synthesized via 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 Eu³⁺ ions. Photoluminescence (PL) studies performed at 394 nm on Eu³⁺ doped ORMOSILs imply that they emit broad blue host emission and the characteristic Eu³⁺ red emissions simultaneously. Also, the samples were excited at the charge transfer (CT) band and this confirmed the existence of an energy transfer path from the host to the Eu³⁺ ions via Ti⁴⁺-O^2--Eu³⁺ bonds. The phonon energy of the host matrix was estimated by phonon sid
