The Matrix

AbstractIn this paper the relationships between the crystal structure, chemical composition and electronic structure of laser materials, and their optical properties are discussed. A brief description is given of the different laser activators and of the influence of the matrix on laser characteristics in terms of crystal field strength, symmetry, covalency and phonon frequencies. The last part of the paper lays emphasis on the means to optimize the matrix-activator properties such as control of the oxidation state and site occupancy of the activator and influence of its concentration.

Energy dispersive x-ray spectroscopy of lowtemperature b¢-Ag8SnSe6 crystalcarried out. Energy dispersive spectrum shows only peaks related to Ag8SnSe6. Experimental optical absorption spectrum and band gap value 0.82 eV are determined. Theoretical calculation of absorption spectrum shows good agreement with experimental studies. Modeling of crystal structure of Ag8SnSe6 argyrodite and interatomic distances calculation are carried out.

The article describes the main features of a new class of colloidal nanoparticles with the electronic structure of semiconductor quantum wells – atomically-thin cadmium selinide CdSe and cadmium telluride CdTe nanosheets with a thickness of 1-2 nm and extended lateral sizes in the range of 100–700 nm. Approaches to the synthesis of such nanostructures by wet chemical methods are considered. A new effect of spontaneous folding induced by ligand exchange has been described.
