Photoluminescence of Porous Silicon Doped with Europium Complexes

Abstract:

Article Preview

Europium (Eu3+)/porous silicon (PS) nanocomposites have been formed by impregnation of PS layer in acetone solution of europium. The surface morphology of samples was characterized by scanning electron microscopy. The photoluminescence (PL) spectrum of samples shows an increased PL intensity of emission peak at 474 nm under excitation of 370 nm. It was found that there is an efficient energy transfer from Tb3+ to Eu3+ and to Silicon nanocrystallites.
