Optical properties of UV-induced color centers in a KY3F 10:Ce3+ crystal

The evolution of color centers induced in a KY3F 10:Ce3+ crystal by UV radiation has been observed and interpreted. It has been revealed that, initially, the UV irradiation of the KY3F10:Ce3+ crystal induces the formation of color centers predominantly of the F-type, which, in a short time period of about ten minutes, are transformed into complex color centers of the F 2-type, as well as into impurity color centers. Based on the data obtained, a diagram of energy states of the crystal, dopant, and color centers has been constructed, on which most probable processes that are caused by electronic transitions occurring in the KYF:Ce3+ crystal after its UV irradiation have been indicated. © 2013 Pleiades Publishing, Ltd

Cyclic voltammetry of tris(2,2-bipyridine)zinc(II) diperchlorate detected by electron spin resonance

Electrochemical transformations of the tris(2,2-bipyridine) complex of zinc(II) perchlor- ate were studied by cyclic voltammetry detected by electron spin resonance (DESR CV), which made it possible to indentify the intermediates formed and to monitor the unpaired electron localization in them. © 2013 Springer Science+Business Media, Inc

Up-conversion luminescence of LaF3:Pr3+ crystal

© Published under licence by IOP Publishing Ltd. LaF3:Pr3+ crystal is proposed as a promising media for an infrared quantum counter in the mid-infrared spectrum range. In this paper it has been shown that this crystal can work as an infrared quantum counter in the range of spectra of about 3 μm at the temperatures 170 K and 210 K with the efficiency of about 5%
