A praseodymium-added zinc oxide film was successfully obtained by dipcoating using zinc acetate dehydrate and praseodymium oxide as starting materialswith 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 decompositionand crystallization of zinc oxide to find the optimum condition for the filmpreparation. In order to obtain the uniform and dense structure of zinc oxidefilm, a coating solution should be prepared to contain diethanol amine/zincmolar ratio = 1. Calcination in an oxygen stream was necessary to removeorganic residues after each dipping. Smaller average value and narrower sizedistribution of grain were observed for the zinc oxide film compared to a disktypepraseodymium-added zinc oxide prepared by a precipitation method.Appreciable non-linear characteristic was confirmed in voltage-current forthe zinc oxide film obtained.
