متن کاملStructure and stability of the (001) alpha-quartz surface.
The structure and surface energies of the cleaved, reconstructed, and fully hydroxylated (001) alpha-quartz surface of various thicknesses are investigated with periodic density functional theory (DFT). The properties of the cleaved and hydroxylated surface are reproduced with a slab thickness of 18 atomic layers, while a thicker 27-layer slab is necessary for the reconstructed surface. The per...
متن کاملOptically stimulated luminescence in synthetic quartz
Optically stiniulated luminescence (OSL). has been studied in synthetic quartz crystals. which had previously been exposed to Jtor X-irradiations. The main emission hands appeared at 380 and -~440 nm. The excitation spectra of these emission bands were now measured and showed both a maximum at 330nm. This maximum coincides with an excitation maximum of the phototransferred thermoluminescence (P...
متن کاملOn the Use of Synthetic Quartz as a Radiation Dosimeter
Quartz obtained from structural materials (bricks, tiles, etc.) is usually employed in retrospective accident dosimetry using the thermoluminescence (TL) technique. However, the TL response can be different depending on the sample due to the different concentration of the impurities in quartz lattice and the glow curves themselves show an enormous variety of shapes. In order to investigate the ...
متن کاملSelected Properties of a Synthetic Quartz Glass-Ceramic
QDT 2005 1 he restoration of missing or compromised tooth structure requires dental materials that offer toothlike esthetics, functionality, biocompatibility, and longevity. Silica-based ceramics (eg, feldspathic porcelain) offer all of these necessities and are the materials of choice for esthetic all-ceramic restorations (eg, laminate veneers, ceramic inlays and onlays, and full-coverage jack...
