Fig. 4. Fluorescence decay profile of Ag@AIE-Y-SOG with different PEI/PSS bilayers and AgNPs sizes (a) 25 nm AgNPs, (b) 40 nm AgNPs, and (c) 85 nm AgNPs. (d) Average fluorescence lifetime ( Created by potrace 1.16, written by Peter Selinger 2001-2019 ) for Ag@AIE-Y-SOG samples with 1 (square), 2 (sphere), and 3 (triangle) PEI/PSS bilayers. (e) Simplified Jablonski diagram for a typical AIE-PS in the vicinity of AgNPs. Σkrad is the summation of intrinsic radiative decay rate in AIE-PS (krad) and radiative decay rate due to the presence of metal NPs (krad@metal). Σknrad is the summation of intrinsic non-radiative decay rate in AIE-PS (knrad) and non-radiative decay rate due to the presence of metal NPs (knrad@metal). The average fluorescence lifetime is defined as Created by potrace 1.16, written by Peter Selinger 2001-2019 = 1/(Σkrad + Σknrad) for a classical fluorophore.
