摘　　要：利用HCI与掺入不同量(NH4)6Mo7O24·4H2O的Na2WO4溶液反应生成的掺杂钼的钨酸沉淀作为前驱体,通过简单的水热方法,合成了过渡元素钼掺杂氧化钨纳米棒,通过XRD、SEM、EDS、TEM和PL等手段对产物进行了表征.研究表明,随着钼的掺杂量的增加,氧化钨纳米棒的尺寸逐渐减小,并且氧化钨纳米棒的荧光发射峰强度也逐渐减弱.Tungsten oxide nanorods doped with molybdenum were synthesized by a facile hydrothermal method using tungstenic acid precipitate doped with molybdenum as precursor, which was prepared by the reaction between HCl solution and Na2WO4 solution immingled different percentages of (NH4)(6)Mo7O24-4H(2)O respectively. The samples of the products were characterized by XRD, SEM, EDX, TEM and PL. The results show that the dimensions of as-synthesized tungsten oxide nanorods gradually decrease with the increase of the percentage of doped molybdenum, the photoluminescence emission peak intensities of them weaken down accordingly.
