Home Resource Center Product Data and Related Literature Inorganic Chemicals Oxides Praseodymium Oxide Pr2O3 for Optical Coating Praseodymium Oxide, Pr2O3 for Optical Coating Overview Praseodymium oxide, Pr2O3, produces medium-index film layers that are transparent throughout the visible region. The films are insoluble and hard. Film Properties of Praseodymium Oxide Pr2O3 Praseodymium oxide films require an electron-beam source to reach evaporation temperature. Amorphous films can be deposited below 150° C substrate temperature. Above ~300° C, the films become crystalline. Physical Properties of Solid Material Praseodymium Oxide Pr2O3 Evaporation Parameters of Praseodymium Oxide Pr2O3 Evaporation Procedure of Praseodymium Oxide Pr2O3 Keep the material in a dry atmosphere, preferably heated to reduce moisture adsorption. Precondition with a low power sweep until spitting and outgassing subside as a rate of 1Å/sec is approached (~15 min). Evaporation is by sublimation. Continue sweeping to prevent burrowing. Applications of Praseodymium Oxide Pr2O3 The medium index value and layer hardness make praseodymium oxide suitable for the intermediate index in a wide-band visible AR coating.
