文摘

Photoluminescence (PL) properties of the peanutlike ZnO microrods synthesized by a hydrothermal method werestudied in the temperature range of 8-300 K. UV, violet, and green peaks, which exhibit blue, S-shaped (red-blue-red), andredshifts, respectively, and the intensity decrease, with an increase of the test temperature, are observed in the PL spectrum. Theexistence of V_o and Zn_i in these microrods is confirmed by X-ray electron spectrometry and electron paramagnetic resonance spectrum,respectively. The origin and different temperature dependence of the UV, violet, and green peaks are discussed.
