Recent Advances in Trifluoromethylation Reactions with Electrophilic Trifluoromethylating Reagents
(Wiley, 2014-10)
Electrophilic trifluoromethylation reactions have been the latest approach to achieve the fluoroalkylation of compounds with newly-discovered reagents, such as the Togni’s (1-trifluoromethyl-1,2-benziodoxol-3-(1 H)-one), ...
Optical spectroscopy of Er3+ and Yb3+ co-doped fluoroindate glasses
(1998-02-15)
Optical absorption, Stokes, and anti-Stokes photoluminescence were performed on Er3+-Yb3+ co-doped fluoroindate glasses. For compounds prepared with a fixed 2 mol % ErF3 concentration and YbF3 contents ranging from 0 to 8 ...

Energy transfer between Pr3+ ions in a fluoroindate glass
(1998-06-01)
The efficiency of energy transfer (ET) between Pr3+ ions in a fluoroindate glass is determined. ET rates, WET, were determined for dilute samples and the results show a dependence of WET on the Pr3+ concentration. ET ...
Giant non-linear absorption in Er3+-doped fluoroindate glass
(1999-06-02)
Non-linear absorption is observed in Er3+-doped fluoroindate glass (in mol% 37InF2:20ZnF2:20SrF2:16BaF2:2GdF2: 2NaF:1GaF3:2ErF3) when the sample is irradiated with a CW laser emitting at 650 nm. An intensity dependence of ...
In Silico Design of Cylindrophanes: The Role of Functional Groups in a Fluoride Selective Host
(Wiley-VCH Verlag, 2020)
Crystallization of fluorindate and fluorogallate glasses
(1997-10-01)
Crystallization of binary InF3-MF2 and GaF3-MF2 (where M = Ba, Sr and Ca) glasses was studied. Characteristic temperatures and kinetic parameters E (activation energy) and n (Avrami exponent) were obtained. Stability against ...
