Description
Summary:[Display omitted] •Te nanopowder was prepared by vibration milling technique.•Nanocomposite films were obtained by binding Te nanopowder with PMMA.•Raman spectroscopy reveals the coexistence of Te and TeO2 crystalline phases.•The responsivity is independent of the wavelength of the incident radiation.•The photocurrent increases linearly with increasing the optical power density.
