(A) Power deposited in the bead (o) and scattered through silica substrate (×) during the absorption stage (TE polarization, λ=532 nm). (B) Total fluorescent power leaving the bead (o) and detectable fluorescent power (×) (λ=597 nm). All power is plotted as a function of bead magnetite concentration (QD volume fraction is constant at 5%, angle of incidence θ=75°, bead diameter is 1.0 μm). Solid and dotted lines correspond to beads positioned 30 nm and 90 nm away from silica. The powers are normalized by the total power available from the incident beam in the silica substrate (for the circular cross-sectional area with a radius equal to the bead radius).
