Abstract Raman spectra of ZnO powders prepared by firing ZnO₂ precipitate were reported in detail for the first time. By comparing the spectra with that of the sample fabricated by another method and analyzing frequency difference between the focused-laser irradiated samples with different firing temperature in preparation, it was concluded that the ～333 cm^-1 peak is ascribed to E₂(high)-E₂(low) and the ～661 cm^-1 peak to its overtone. In addition, a new interpretation for the observed Raman peaks between 400 and 500 cm^-1 in ZnO₂ powders was presented based on the IR data and ab initio calculation.
