Final report on subcontract B076260
- Oregon State Univ., Corvallis, OR (United States). Dept. of Chemistry
Work continued on synthesis of borates A{sub 6}MM`(BO{sub 3}){sub 6}, where A=Sr or Ba, M=lanthanide, Y, Sc, In, or Ca, and M`=heavier lanthanide, Sc, Cr, Mn, Fe, Co, In, Ga, Al, Ru, Rh, Ti, Zr, Hf, or Sn. Their structures are discussed, in particular Sr{sub 6}HoSc(BO{sub 3}){sub 6}. Other new borates and gallates are being studied. In the fluoride program, single crystals were grown of RbY{sub 2}ScF{sub 10}; samples codoped with Cr and Nd ions show only Nd fluorescence when excited by Ar laser. Structures of the (laser) materials LiCaGaF{sub 6}, LiSrAlF{sub 6}, and Sr{sub 2}ScF{sub 7}, and fluorescence of the Cr-doped form of the last fluoride were determined. Finally, work on frequency converters include the following: Optical nonlinearities of new borates were calculated. New borates containing Be are being synthesized: SrBe{sub 2}(BO{sub 3}){sub 2}, BaCuB{sub 2}O{sub 5}. Structures of Rb{sub 2}Na(NO{sub 3}){sub 3}, RbNO{sub 3}, and other nitrates will be used to determine the nitrate group`s hyperpolarizability coefficient. Work on organic frequency converters covered L-arginine derivatives, lactones, etc.
