FIG. 1.

(a) Experimental PL rise for high (squares) and low (circles) inverted and normalized for clarity, and PL decay (triangles). The dashed lines are the single exponential fits of the experimental data. (b) Analysis of the spatial energy distribution of the pumping spot on the surface of a waveguide. (c) Scheme of the experimental setup built for the time resolved experiments.

FIG. 2.

PL emission (dashed line) corresponding to the transition. It has been obtained by pumping at low at 488 nm. The solid curve shows the extracted spectrum for the excitation cross section of the transition. The dashed-dotted gray curve shows the spectrum of the pump laser used in the present study. (Inset panel) Difference of the inverses of the rise and decay lifetimes as a function of for samples A (gray circles) and B (black triangles). The dashed curve corresponds to the fit using Eq. (2).

FIG. 3.

as a function of (in log-log scale) for samples A (gray circles) and B (black triangles) together with their respective fits using Eq. (1). The different achievable concentration levels are also represented as horizontal lines. The inset represents the low set of data for sample B in a linear scale together with a linear fit using the low flux approximation of Eq. (1).
