Popis:	A praseodymium-added zinc oxide film was successfully obtained by dip coating using zinc acetate dehydrate and praseodymium oxide as starting materials with ethanol as a solvent and one of ethanol amines as an aid for film preparation.Several sets of ethanol amines were examined for their thermal decomposition and crystallization of zinc oxide to find the optimum condition for the film preparation. In order to obtain the uniform and dense structure of zinc oxide film, a coating solution should be prepared to contain diethanol amine/zinc molar ratio=1. Calcination in an oxygen stream was necessary to remove organic residues after each dipping. Smaller average value and narrower size distribution of grain were observed for the zinc oxide film compared to a disktype praseodymium-added zinc oxide prepared by a precipitation method.Appreciable non-linear characteristic was confirmed in voltage-current for the zinc oxide film obtained.
