抄録
Photoluminescent materials which show multi-wavelength luminescence have potential applications in tem-perature sensing device. In this study, Mn2+-doped ZnCN2 phosphor was prepared by ammonia nitridation of Zn-Mn oxalate precursors in the presence of carbon nitride. Upon UV excitation, it showed photoluminescence band at 580 nm due to isolated Mn2+ ions as well as minor broad emission bands at 500 and 670 nm due to anion vacancies and Mn-Mn pairs in the ZnCN2, respectively. Since the intensities of the luminescent bands had different temperature dependencies, and the total luminescence color changed from orange at 80 K to yellow green at 500 K.
