## Abstract The influence of annealing atmosphere on the optical properties of flowerβlike ZnO is investigated. The flowerβlike ZnO is composed of nanosheets. Annealing at 500Β°C results in the increase of the thickness of nanosheets and the enhancement of UV emission. PL spectra results show that t
Influence of the thermal annealing atmosphere and the ZnO layer thickness on the photoluminescence properties of ZnS-core/ZnO-shell one-dimensional (1D) radial heterostructures was investigated. ZnS nanowires were synthesized by thermal evaporation of ZnS powders and then coated with ZnO by using th
