摘要: CdTe nanocrystals (NCs) capped with thioglycolic acid (TGA) were synthesized via a microwave-assisted method. The chemiluminescence (CL) of NCs induced by directly chemical oxidation and its size-depended surfactant-sensitized effect in aqueous solution then investigated. It was found that oxidants, especially hydrogen peroxide potassium permanganate, could oxidize to produce strong CL emission basic conditions. oxidized displayed size-dependent intensity increased along increasing the sizes NCs. Moreover, could, if surfactants CTAB or β-cyclodextrin added above system, be sensitized some degree. is mainly contributing formation aggregate nanostructure micellar micronanoenvironment, respectively. possible mechanisms further examined means photoluminescence spectra, transmissi...
