Annealing was carried out in argon atmosphere at 450กใC for 60 minutes of the films. To investigate the composition and stoichiometry of sprayed as-deposited and annealed Lu2O3 thin films, depth profile studies using X-ray photoelectron spectroscopy (XPS) was done. Nearly stoichiometric was observed for both annealed and as-deposited films in inner and surface layers. %K Lu< %K sub> %K 2< %K /sub> %K O< %K sub> %K 3< %K /sub> %K Depth Profiling %K X-Ray Photoelectron Spectroscopy %K Thin Films %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=129378
