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...
