Abstract

The exciton photoluminescence of zinc oxide is studied in the temperature range 5–300 K. The formation of the exciton emission band profile in the spectra of undoped crystals, high-purity powder, and thin ALD films 4–450 nm in thickness at 300 K and at excitation by a He–Cd laser is analyzed. The effects of the photodesorption and photoadsorption of atmospheric oxygen on the exciton emission spectrum of a ZnO powder in sequential vacuum–air cycles have been studied at room temperature during continuous excitation by a He–Cd laser.

室温下ZnO近边缘辐射的性质

摘要

在5–300 K的温度范围内研究了氧化锌的激子光致发光。在300 K时，未掺杂的晶体，高纯度粉末和ALD薄膜厚度为4–450 nm时，激子发射带分布的形成。并在He-Cd激光激发下进行分析。在连续的真空-空气循环中，研究了大气氧的光解吸和光吸附对ZnO粉末的激子发射光谱的影响，该过程在室温下由He-Cd激光器连续激发期间进行了研究。
