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 hy-drothermal method using tungstenic acid precipitate doped with molybdenum as precursor, which was prepared by the reaction between HC1 solution and Na2WO4 solution immingled different percentages of (NH4)6Mo7O24·4H20 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.
