摘要：

A comparative study of the luminescent properties of Y2O3 Eu3+ phosphor powders and thin films sputtered from targets prepared from combustion synthesized powders is reported Thin films of (Yo(96)Eu(0 04))(2)O-3 were deposited on silicon substrates Films deposited at 600 degrees C had both monoclinic and cubic phases of Y2O3 which developed to an oriented cubic phase after annealing Films and powders showed a linear dependence of the intensity of the 5D(7)-> F-7(2) (611 nm) transition with temperature in the range 26-660 degrees C with an average rate of change of 18 x 10(-4) degrees C-1 The rate of change appears to be dependent on the Eu3+ concentration This work shows that these thin films can be used as thermographic phosphors for remote temperature measurements (c) 2010 Elsevier B V All rights reserved
