Sonochemical Synthesis ofEr3+-Doped ZnO Nanospheres with Enhanced Upconversion Photoluminescence

[摘要] Er3+-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-preparedEr3+doped ZnO nanospheres show enhanced photoluminescence and upconversion photoluminescence properties compared with pure ZnO.
