Doping of porous silicon with terbium organic complex

A simple but effective doping method to introduce functional organic molecu les and metal ions into porous silicon with relatively simple organic compl exes was developed. After porous silicon was doped with a Tb-sulfosalicylic complex, it emits bright green emission when excited with UV light. The ph otoluminescence (FL) spectrum shows that only Tb3+ ions emit efficiently wh ile the luminescence of porous silicon and organic ligands is almost thorou ghly quenched. Based on the Fourier transform infrared and PL measurements, it is proposed that Tb3+ complex was physically adsorbed into pores of por ous silicon.
