Název v původním jazyce

Production and characterization of LiYF4 oxifluoride glass ceramics prepared by electron beam evaporation and pulsed laser deposition

Popis výsledku v původním jazyce

Oxifluoride glass ceramics composed of rare-earth ions (Er3+and Pr3+) doped LiYF4and SiO2-Al23 based amorphous glass, are produced by combination of the Electron Beam Evaporation (EBE) and Pulsed Laser Deposition (PLD) methods. These structures are prepared in novel advanced vacuum deposition system built in Institute of Physics AS CR. High-purity powder targets are deposited on pre-heated amorphous SiO2substrates to create strain-free (1) layered structures with alternate glass/fluoride layers and (2)structures with fluoride clusters incorporated in the glass matrix by combining both the EBE and PLD methods. Fluorides are deposited via EBE using a 2kW Mini E-beam evaporator (Tectra), while oxides and rare-earth dopants are deposited via PLD method bymeans of pulsed Nd:YAG laser operated at wavelength of 266 nm.The scope of this work lies in observation of fluorescence properties of the structures and their dependency on the substrate deposition temperature.
