scheme of the effects of the dopant precursor on the resulting ZnO/PAA nanohybrids. The interaction is threefold: affecting the architecture of the mesospheres, of the ZnO nanocrystal size and the amount and nature of the gap states in the ZnO nanocrystals. The latter can be radiative or non-radiative and related to levels of the dopant itself or to native defects of ZnO (vacancies and interstitials).
