AB  - The polymer nanocomposite ZnS/Poly (methylmethacrylate) was prepared by the solution casting method and its structural and optical properties were investigated using XRD, SEM, TEM, HRTEM, and Raman spectroscopy. The basic material, ZnS, has the cubic structure and its crystallite size was estimated to be 2.3 nm, which implies that a strong confinement regime is in effect. Analysis of Raman spectra was performed using the fitting procedure based on effective medium theory. As a result, the surface optical phonon (SOP) mode was detected. It was found that the shape and position of the SOP mode depend on the type of the composite.

AB  - Calcium fluoride - CaF2 single crystals were grown using the Bridgman technique. By optimizing growth conditions,  lt 111 gt -oriented CaF2, crystals up to 20 mm in diameter were grown. Number of dislocations in CaF2 crystals which were made by the method of Bridgman was 5x10(4) - 2x10(5) per cm(2). In this paper we used XRD, Raman spectroscopy and the measurement of transmission in the mid IR-range to investigated structural and optical properties of obtained CaF2 single crystals.

AB  - In this work single crystals of bismuth germanium oxide (Bi12GeO20) have been grown by the Czochralski method. Growth conditions were studied. The critical diameter and the critical rate of rotation were calculated. Suitable polishing and etching solutions were determined. The structure of the Bi12GeO20 has been investigated by X-ray diffraction, Raman and FTIR spectroscopy. The obtained results are discussed and compared with published data. On the basis of the measurements by Raman spectroscopy, we observed 15 modes.
