Transmission electron microscopy (TEM), atomic force microscopy (AFM), X-ray diffraction (XRD), energy dispersive X-ray (EDX), scanning electron microscopy (SEM), diffuse reflectance spectroscopy (DRS), and Fourier transform infrared (FTIR) spectroscopy were applied to evaluate the tin dioxide nanoparticles (SnO NPs) amalgamated by the sol-gel process. XRD was used to examine the tetragonal-shaped crystallite with an average size of 26.95 (±1) nm, whereas the average particle size estimated from the TEM micrograph is 20.59 (±2) nm. A dose-dependent antifun3al activity was performed against two fungal species, and the activity was observed to be increased with an increase in the concentration of SnO NPs. The photocatalytic activity of SnO NPs in aqueous media was tested using Rhodamine 6G (Rh-6G) under solar light illumination. The Rh-6G was degraded at a rate of 0.96 × 10 min for a total of 94.18 percent in 350 min.
透射电子显微镜（TEM）、原子力显微镜（AFM）、X 射线衍射（XRD）、能量色散 X 射线（EDX）、扫描电子显微镜（SEM）、漫反射光谱（DRS）和傅里叶变换红外（FTIR）光谱被应用于评估通过溶胶-凝胶工艺结合的二氧化锡纳米粒子（SnO NPs）。XRD 用于检测具有平均尺寸为 26.95（±1）nm 的四方晶型结晶，而从 TEM 显微照片估算的平均粒径为 20.59（±2）nm。针对两种真菌进行了剂量依赖性抗真菌活性测试，观察到随着 SnO NPs 浓度的增加，活性增加。在太阳光照射下，在水介质中测试了 SnO NPs 的光催化活性。在 350 分钟内，Rh-6G 的降解速率为 0.96×10 min，总降解率为 94.18%。
