Abstract

Tellurium oxide is an interesting semiconductor metal oxide with a variety of fascinating photoelectric properties. The method of thermal oxidation of tellurium metal in air was used to make TeO2 nanowires and rods. This paper introduces a facile method to synthesize TeO2 nanoparticles directly from tellurium powder in NH4OH solution. The TeO2 nanoparticles are monodisperse, uniform and high density. The growth mechanism of the TeO2 nanoparticles was proposed and debated. This material has a good ability to absorb infrared light with a wavelength of 800 nm. The infrared photosensing properties of this nanomaterial were investigated and compared to those of recent studies.
