Identification of lowest excited states in the organometallic iron-nitrile complexes
(1999)
Electronic absorption spectra for the complexes [CpFe(dppe)NC-R]PF6 R = CH2-C6H4-ON3P3(OC 6H4t-Bu)5 (1), R = CH2-C6H4-OH (2) and R = CH3 (3) in different solvents have been measured. The two absorption bands at the lowest ...
Upconversion luminescence in Er3+ doped Ga10Ge 25S65 glass and glass-ceramic excited in the near-infrared
(2013-02-28)
The infrared-to-visible frequency upconversion was investigated in Er 3+-doped Ga10Ge25S65 glass and in the transparent glass-ceramic obtained by heat-treatment of the glass above its glass-transition temperature. ...

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 ...

Ytterbium-induced energy-transfer upconversion enhancement in Nd3+/Pr3+-codoped PbGeO3-PbF2-CdF2 glass excited at 810nm
(Elsevier B.V., 2006-01-01)
The effect of ytterbium ions upon energy transfer (ET) excited upconversion emission in Nd3+/Pr3+ -codoped PbGeO3-PbF2-CdF2 glass under 810 nm diode laser excitation is investigated. The results revealed that the presence ...
Red-green-blue upconversion emission and energy-transfer between Tm3+ and Er3+ ions in tellurite glasses excited at 1.064 mu m
(Elsevier B.V., 2003-02-15)
Red, green, and blue emission through frequency upconversion and energy-transfer processes in tellurite glasses doped with Tm3+ and Er3+ excited at 1.064 mum is investigated. The Tm3+/Er3+-codoped samples produced intense ...
