Herein we report the hydrothermal synthesis, characterization and biological applications of h-MoO₃ and silver doped MoO₃ nanoparticles (NPs). The phase formations of the synthesized NPs were identified using X-Ray diffraction studies and vibrational spectral studies. The average crystallite size of the NPs tends to decrease with increase in doping concentration. The surface morphology and the elemental composition of the nanoparticles were observed from SEM and EDAX analysis. The crystallite nature was obtained from HRTEM images. The band gap energies obtained from UV-DRS spectra for h-MoO₃ (3.26 eV) were found to decrease as the concentration of the dopant (Ag) increases (3.22–2.76 eV). The antibacterial activity of the prepared nanoparticles was tested against some gram positive and gram negative bacterial strains viz., Staphylococcus aureus and Bacillus cereus, Citrobacter koseri and Pseudomonas aeruginosa respectively. Also their seed germination properties were studied on foxtail and finger millet seeds for a period of seven days.

在此，我们报告了 h-MoO ₃和银掺杂的 MoO ₃纳米粒子 (NPs)的水热合成、表征和生物学应用。使用 X 射线衍射研究和振动光谱研究确定了合成 NPs 的相形成。随着掺杂浓度的增加，纳米颗粒的平均晶粒尺寸趋于减小。通过SEM和EDAX分析观察纳米颗粒的表面形貌和元素组成。微晶性质是从 HRTEM 图像中获得的。从 h-MoO _{3 的}UV-DRS 光谱获得的带隙能量发现 (3.26 eV) 随着掺杂剂 (Ag) 浓度的增加 (3.22–2.76 eV) 而降低。制备的纳米颗粒分别对一些革兰氏阳性和革兰氏阴性菌株，即金黄色葡萄球菌和蜡状芽孢杆菌、克氏柠檬酸杆菌和铜绿假单胞菌进行了抗菌活性测试。此外，它们的种子发芽特性在狐尾和指黍种子上进行了为期 7 天的研究。
