摘要：
We prepared PrxZn1-xO nanopowder using a combustion method. The sample was characterized by XRD, TEM, XPS, UV-visible and PL spectroscopy. The prepared PrxZn1-xO nanopowder had a good photon absorption performance in the range of 200-800 nm wavelength. Moreover, the 4f(2) electronic configuration of trivalent Pr3+ ions was revealed from the diffuse reflectance spectra. The single crystalline particle size was about 20-70 nm based on the TEM observation. A quantum size effect of the PrxZn1-xO nanopowder was also noted. (C) 2009 Elsevier B.V. All rights reserved.
