Abstract:

The objectives of this investigation are to grow cubic cm-size crystals of cubic perovskites activated with divalent or tetravalent dopant cations which will substitute directly without charge compensation and to determine the fluorescence characteristics of these materials. The perovskite of primary interest is BaZrO3 and of next interest is SrTiO3. Dopant ions of interest include di- and tetra-valent rare earths and tetravalent manganese. Author
