Abstract:

Research was conducted on electrooptic materials. Single crystals of Bi4Ti3O12 are grown in the correct platy habit and optimization of the growth condition is studied. The new ferroelastic materials isopropyl ammonium chloroplatinate and isopropyl ammonium chlorostannate have been grown as quite good quality crystals and many properties have been measured. The main effort has gone into preparation of coatings on crystals and glasses and their characterization. RF sputtering has been shown to be a tremendously versatile tool for the preparation of both crystalline and noncrystalline layers of many compositions. By controlling process parameters in the sputtering chamber, composition and valence state in the sputtered layers can be controlled. Glass surface coatings and glass surface strengthening have been prepared by CVD, microwave plasma, and ion exchange techniques.
