Optical and structural characterizations of Cu+-doped KCl films

TSDC spectroscopy of relaxational and interfacial phenomena

“…A variety of natural minerals, such as amethyst [94], sapphire [95], stilbite [96], calcite, dolomite, quartz [97], clays [98], mordenites [99,100], cretaceous strata [101], and synthetic solids, such as ceramics doped with CuO, FeO and TiO 2 [102], silicas, silicates and other compounds with silica [103][104][105][106], different crystals [107][108][109][110][111][112] and polycrystalline structures [113,114], disordered materials [115], thin films [116][117][118][119][120][121], ferrites [122], metal fluorides [123][124][125][126][127][128][129] and solid solutions based on fluorides [130][131][132][133][134][135], was investigated by the TSDC method.…”

Heavily Cu+-doped amorphous PbCl2films and aggregation of Cu+ions due to crystallization observed by UV spectroscopy

“…One of the interests in producing film material rather than growing single crystals is the possibility of introducing high concentration impurities. For example, Cu + -doped KCl films with the Cu + concentration ranging from 10 20 to 10 21 cm −3 have been attained (for the purpose of device application such as ultraviolet (UV) optical filters) by resistive co-evaporation of KCl-CuCl mixed powders with nominally 1-15 mol% CuCl concentration [1]. Recently, we doped CdI 2 films with trivalent Bi 3+ ions up to 10 mol% of cation concentration [2], despite the different valencies between the host and guest cations.…”
