In the present work, for the first time, we report γ-MnS films with a 3D microsphere morphology prepared through a chemical bath deposition technique at low temperature under aqueous conditions. The X-ray diffraction study confirmed the formation of wurtzite phase γ-MnS. Growth temperature induces a change in the morphology of γ-MnS films from microspheres to microflakes, which may be due to the difference in the nucleation process. The obtained γ-MnS microspheres have a surface area of ∼25 m2 g−1. The photoluminescence spectra show a strong yellow emission band centered at about 550 nm. The obtained microsphere ensemble plays a crucial role in influencing the magnetic behavior of γ-MnS films. The highest coercive field (3320 Oe) and saturation magnetization (17 emu g−1) were obtained for γ-MnS microspheres prepared at 60 °C.

具有3D微结构的γ-MnS膜:合成,微结构,光学和磁性的综合研究

在本工作中,我们首次报道了在低温,水性条件下通过化学浴沉积技术制备的具有3D微球形态的γ-MnS膜。X射线衍射研究证实了纤锌矿相γ-MnS的形成。生长温度会引起γ-MnS薄膜的形态从微球到微薄片的变化,这可能是由于成核过程的差异所致。所获得的γ-MnS微球的表面积为〜25m 2 g -1。光致发光光谱显示出以约550 nm为中心的强黄色发射带。所获得的微球集合体在影响γ-MnS薄膜的磁行为中起着至关重要的作用。最高矫顽场(3320 Oe)和饱和磁化强度(17 emu g -1)是在60°C下制备的γ-MnS微球。
