Dynamics of upconversion photoluminescence in Ge-Ga-S: Er3+: application of quadrature frequency resolved spectroscopy
Original language description
Quadrature frequency resolved spectroscopy (QFRS) on green (550 nm) upconversion photoluminescence (UCPL) of Ge-Ga-S: Er3+ glasses pumped at 975nm revealed double-peaked spectra with long lifetime tau1 ranging from 0.2 to 2ms and short lifetime tau2 approximate to several tens of us. The results are analysed in terms of the transfer function derived by linearizing rate equations for a three-level model. The tau1 component is attributed to the relaxation at the intermediate level 4I11/2 of Er3+ ions andthe tau2 component, to that at the upper 4S3/2 manifold. The dominance of energy transfer upconversion over excited state absorption in the UCPL manifest itself as a greater dependence of (1) on the pump power and a lower ratio of the components of (2) to (1) in the QFRS spectra of a heavily Er-doped sample.
