Controlled emission and coupling of small-size YAG:Ce3+ nanocrystals to gold nanowire
M. D. Birowosuto, Isnaeni, C. de Mello Donega +1
We report a controlled emission of Ce3+ ions inside single Yttrium Aluminum Gar- net Y3Al5O12 (YAG:Ce3+) nanocrystals with a diameter of 22 +- 10 nm as a result of a coupling of a…
The observation of electron trap liberation in MgF doped with Yb using a two-color excitation experiment
P. S. Senanayake, J. P. R. Wells, M. F. Reid +3
We utilize the optical transitions of Yb excited by an ultraviolet optical parametric amplifier to probe electron trap liberation in MgF via the observation of a photo…
Impurity-trapped excitons and electron traps in CaF:Yb and SrF:Yb probed by transient photoluminescence enhancement
P. S. Senanayake, J. P. R. Wells, M. F. Reid +3
CaF:Yb and SrF:Yb crystals have been investigated by a two-color UV + IR transient photoluminescence enhancement technique. The enhancement gives information…
Transient photoluminescence enhancement as a probe of the structure of impurity-trapped excitons in CaF:Yb
Michael F. Reid, Pubudu S. Senanayake, Jon-Paul R. Wells +5
We demonstrate a direct measurement of the energy levels of impurity-trapped excitons in CaF:Yb. The radically different radiative decay rates of the lowest exciton stat…
The unusual temperature dependence of the Eu fluorescence lifetime in CaF crystals
C. K. Duan, A. Mejerink, R. J. Reeves +1
Fluorescence lifetimes of Eu doped in CaF are measured at various temperatures between 4K and 450K. The lifetime increases with between 100K and 300K, in contrast to the…
