Time dependence of AgL samples reflectance change upon irradiation with the UV-light source. A – Ag(PiPCO) with data fit the best to a monoexponential decay function y = y0 +A e(-x/t) with the following parameters: y0= 25.72 ± 0.21; A = 6.45 ± 0.29; t = 37.34 ± 4.55; χ2 = 0.05669 and R2 = 0.9943. B – Ag(MCO), best fit to a monoexponential decay function y = y0 +A e(-x/t) with the following parameters: y0 = 24.48 ± 0.17; A = 9.02 ± 0.34; t = 19.03 ± 2.24; χ2 = 0.09001 and R2 = 0.99577.
