ROOM TEMPERATURE LASER ACTION AND Q-SWITCHING OF F-AGGREGATE COLOR CENTERS IN LiF

Energy transfer among color centers in LiF crystals

In colored LiF crystals there are many absorption and emission bands which cover a wide region of the spectrum from 200 up to 1 300 nm without breaking the continuity. In the frame of these favourable conditions we have performed some experiments of energy transfer among various color centers. The results indicate the existence of efficient exchanges of radiative energy among several bands by u...

Color centers beyond ion range in LiF crystals irradiated with Ni ions

LiF crystals exposed to swift heavy ions exhibit unexpected coloration phenomena at a depth up to 3 mm beyond the ion range. The induced color centers were investigated by thermo-stimulated luminescence, optical absorption, and nuclear magnetic resonance (NMR) spectroscopy. The crystals were irradiated with various ions from C to U at the UNILAC accelerator (see [1] and references therein). The...

FORMATION OF F2 - COLOR CENTERS IN LiF MONOCRYSTALS BY ELECTRON IRRADIATION

Formation conditions, optical non-linear properties and some applications of F2 color centers in LIF monocrystals are investigated.

Effect of Calcination Temperature and Li / TFA Molar Ratio on Morphology and Phase of Lithium Fluoride Nanoparticles Produced by Fluorolytic Sol-Gel Method

In this research, synthesis of lithium fluoride (LiF) nanoparticles  by fluorolytic sol-gel method has been studied. Moreover, the effect of lithium ion to fluorine source molar ratio and calcination temperature on particle size and phase of LiF nanoparticles were investigated. Lithium acetate (C2H3LiO2), trifluoroacetic acid (TFA), ethylene glycol monobutyl ether and oleic acid were used as so...
