Frequency upconversion involving triads and quartets of ions in a Pr3+/Nd3+ codoped fluoroindate glass
(2002-09-15)
Frequency upconversion (UC) processes involving energy transfer (ET) among Nd 3+ and Pr 3+ ions in a fluoroindate glass are reported. In a first experiment, the excitation of Pr 3+ [transition 3H 4→ 1D 2] and of Nd 3+ ...
Solvent effects on the reactivity of fluorenyl nitrenium ion with DNA-like probes
(Universidad de Belgrano - Facultad de Ciencias Exactas y Naturales - Proyectos de Investigación, 2006)
Laser Flash Photolysis (LFP) experiments carried out on 2-azidofluorene in aqueous systems generate 2-fluorenyl nitrenium ion (λmax = 450 nm) which decays with first order rate constant and is quenched with 2′-deoxyguanosine ...

Upconversion ultraviolet random lasing in Nd 3+ doped fluoroindate glass powder
(2011-03-14)
An upconversion random laser (RL) operating in the ultraviolet is reported for Nd 3+ doped fluoroindate glass powder pumped at 575 nm. The RL is obtained by the resonant excitation of the Nd 3+ state 2G 7/2 followed by ...
