-doped ZnO nanospheres have been synthesized via a sonochemical conversion process. The formation mechanism of these nanocrystals is connected with the sonochemical effect of ultrasound irradiation. The as-prepared doped ZnO nanospheres show enhanced photoluminescence and upconversion photoluminescence properties compared with pure ZnO.
