• photoluminescence

A simple but effective doping method, immersion method, was presented. Rare earth complexes [Na3Tb(DPA)(3)center dot 9H(2)O and Na3Eu(DPA)(3)center dot 9H(2)O] were introduced into porous silicon (PS), where H(2)DPA 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.
