在环境透射电子显微镜中，在氧气气氛中加热钨丝，生长出用于电子器件的WO3纳米棒，这允许观察生长过程，以揭示WO3纳米棒的生长机制。纳米棒的初始生长不包括氧化钨，而是晶体钨。然后将所形成的晶体钨纳米棒氧化，从而形成氧化钨纳米棒。此外，预计纳米棒通过钨丝上的天然表面氧化物层中的裂纹生长。
WO3 nanorods targeted for applications in electric devices were grown from a tungsten wire heated in an oxygen atmosphere inside an environmental transmission electron microscope, which allowed the growth process to be observed to reveal the growth mechanism of the WO3 nanorods. The initial growth of the nanorods did not consist of tungsten oxide but rather crystal tungsten. The formed crystal tungsten nanorods were then oxidized, resulting in the formation of the tungsten oxide nanorods. Furthermore, it is expected that the nanorods grew through cracks in the natural surface oxide layer on the tungsten wire.
