The preparation of homogenous, large area thin layers of tellurium on thin polyethylene foils is described. The tellurium was formed by room temperature decomposition of electrochemically generated H2Te. Pre-treatment of the polyethylene substrates with KMnO4 to give a Mn-oxide layer was found to improve the Te adhesion and homogeneity. Optical characterization of the layers was performed using UV/VIS/NIR spectroscopy. Such coatings have favorable characteristics for use as solar radiation shields in radiative cooling devices. The simplicity of generation of the very unstable H2Te was also exploited to demonstrate formation of size-quantized CdTe nanocrystals. (C) 2000 Elsevier Science S.A. All rights reserved.
