Photo- and cathodoluminescence of the cetylpyridinium chloride: ZnO nanocomposites
Source abstract
Abstract
The cathodoluminescence and photoluminescence (PL) spectra of ZnO nanoparticles (NPs) embedded into the cetylpyridinium chloride (CPCL) matrix were studied. The composites were obtained by drying an aqueous suspension of CPCL and ZnO NPs, with NaCl and with NaOH additives. We observed that only NaOH addition lead to a significant increase in the PL intensity which we attribute to the surface chemistry of the ZnO NPs. We propose that thin ZnOH2 and Na2ZnO2 layers form on the surface of the NPs; these layers present an increased number of oxygen vacancies, which act as emitting centres.
