In recent years, chalcogenide glasses such as ZnS or ZnSe have attracted much attention due to their excellent optical properties. The structure of chalcogenide materials is part of the important factors affecting their optical properties. In this paper, the magnetic environment was set to control the growth structure of nano film in the process of deposition, which could be affected the optical properties of Co-doped ZnS (ZnS:Co) nano-film. All films were prepared by pulsed laser deposition (PLD). The results of XRD and Raman proved that the structure of the film was changed by the magnetic field. A broader band fluorescence characteristic in the film was shown by PL spectrum, which revealed a substantially improvement of the optical properties for this material. Under the condition of the magnetic field, consistency between FDTD (Finite difference time domain method, FDTD) simulation and experimental results further confirmed the improvement of the optical properties. The findings warrant that the optimized ZnS:Co thin films could be applied to develop efficient optical waveguide devices and laser gain media in the infrared field.

近年来，诸如ZnS或ZnSe的硫属化物玻璃由于其优异的光学性能而引起了很多关注。硫族化物材料的结构是影响其光学性能的重要因素的一部分。本文通过设置磁性环境来控制纳米膜在沉积过程中的生长结构，这可能会影响掺杂Co的ZnS（ZnS：Co）纳米膜的光学性能。所有薄膜均通过脉冲激光沉积（PLD）制备。XRD和Raman的结果证明薄膜的结构被磁场改变了。PL光谱显示了膜中较宽的带荧光特性，这表明该材料的光学性能大大改善。在磁场条件下 FDTD（有限差分时域方法，FDTD）模拟与实验结果之间的一致性进一步证实了光学性能的改善。研究结果表明，优化的ZnS：Co薄膜可用于开发红外领域中的高效光波导器件和激光增益介质。
