Abstract

Tin-doped zinc sulfide was coated onto glass plates and subjected to a post-air annealing treatment at 300 °C for 2 h. The air-annealed thin films were characterized for observing the tailoring in structural, surface, chemical, optical, photoluminescence, and magnetic properties due to annealing. The properties of thin films after air-annealing were compared with as-synthesized Kumar et al. (J. Supercond. Novel Magn. 32(6), 1725-1734, 2019), and vacuum-annealed Kunapalli et al. (Opt. Mater.114, 110961, 2021) thin films. Annealing in presence of air leads to finer crystallite structures of ZnS thin films. The air annealing also enhanced the transmittance property of the thin films. Two prominent peaks at 420 nm and 440 nm were observed in photoluminescence spectra. From magnetic studies, it was found that the films were paramagnetic in nature, and magnetization increased with an increase in the applied field.

掺锡ZnS薄膜的结构、光学和磁性能:后退火的作用

将掺杂锡的硫化锌涂覆在玻璃板上，在300℃下进行2 h的空气后退火处理。对空气退火薄膜进行了表征，观察到退火后薄膜在结构、表面、化学、光学、光致发光和磁性等方面的变化。Kumar et al. (J. Supercond.)。新材料学报，32(6)，1725-1734,2019)，和真空退火Kunapalli et al. (Opt.材料，114,110961,2021)薄膜。在有空气存在的情况下，退火使ZnS薄膜的晶体结构更精细。空气退火还提高了薄膜的透光性能。在420 nm和440 nm处观察到两个显著的光致发光峰。从磁性研究中发现，薄膜本质上是顺磁性的，磁化强度随外加磁场的增大而增大。
