Keywords： porous silicon

A simple but effective doping method,immersion method,was presented.Rare earth complexes[Na_3Tb(DPA)_3·9H_2O and Na_3Eu(DPA)_3·9H_2O]were introduced into porous silicon(PS),where H_2DPA is 2,6-dicarboxy pyridine acid.Rare earths were proved to dope into PS effectively by photoluminescence(PL)and X-ray energy dispersive spectroscopy(EDS).And the prepared hybrid samples of PS/RE were found to emit intense room-temperature red and green luminescence while the luminescence of porous silicon are almost thoroughly quenched.
