测量了在25K下经剂量为5Gy的X射线辐照的两组氧化锌(ZnO)晶体在25～280K范围内的热释光发光光谱。结果表明:ZnO晶体的低温热释光光谱的发光带的中心波长分别为600,670nm和727nm,其中,中心波长为727nm的发光带同其他2个发光带发光谱线在150K左右峰温约有20K的差别,反映了晶体内部缺陷的转型过程。两组ZnO晶体的热释光谱差异表明,晶体的热释光对样品的生长条件及样品后续处理的条件非常敏感。 The thermoluminescence spectra of two groups of zinc oxide (ZnO) crystals irradiated by X-ray at a dose of 5 Gy at 25K in the range of 25-280K were measured. The results show that the center wavelength of luminescence bands of low temperature TL luminescence spectra of ZnO crystals are 600, 670 nm and 727 nm, respectively. The luminescence band of 727 nm central wavelength and the other two luminescence bands have a peak temperature of about 20K The difference reflects the transformation process of internal defects in the crystal. The difference of the thermoluminescence spectra of the two groups of ZnO crystals shows that the thermoluminescence of the crystal is very sensitive to the growth conditions of the sample and the subsequent processing conditions of the sample.
