摘要
A simple but effective doping method, immersion method, was presented. Rare earth complexes [Na3Tb（DPA）3·9H2O and Na3Eu（DPA）3·9H2O] were introduced into porous silicon （PS）, where H2DPA 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.
