(A) UV/vis absorption curves of DPBF dye comixed with 1.1 × 10–7 M of hypericin β-cyclodextrin complex. (B) TSL and (C) TSL pretreated with NIR (λ = 785 nm, 500 mW, 60% power intensity) for 30 min following consecutive irradiation with yellow LED (587 nm, 1.2 mW/cm2) for several time intervals. (D) The corresponding reduction in the absorption intensity of DPBF was measured at 415 nm (n = 3).
