1：Experimental Design and Method Selection:

The study involved the synthesis of colloidal Ag2S/TGA QDs with average sizes of 2.2 nm and 3.7 nm, and their conjugation with ICG J-aggregates. The spectral properties of these hybrid associates were investigated using absorption and luminescence spectroscopy.

2：2 nm and 7 nm, and their conjugation with ICG J-aggregates. The spectral properties of these hybrid associates were investigated using absorption and luminescence spectroscopy. Sample Selection and Data Sources:

2. Sample Selection and Data Sources: Colloidal Ag2S/TGA QDs were prepared using a synthesis technique involving the infusion of two precursors. ICG J-aggregates were obtained by keeping an aqueous ICG solution at a concentration of 10?3 mol/L at a temperature of 65-67 ?C for 32 hours.

3：List of Experimental Equipment and Materials:

Transmission electron microscope (TEM) Libra 120 (CarlZeiss, Germany) for determining colloidal QDs size, automated spectral complex based on a diffractive monochromator MDR-23 (LOMO) for luminescence spectra and luminescence excitation spectra measurements, TimeHarp 260 time-correlated single-photon counting board (PicoQuant, Germany) for studying the nanosecond decay of Ag2S/TGA QDs luminescence.

4：Experimental Procedures and Operational Workflow:

The synthesis of Ag2S/TGA QDs involved mixing aqueous solutions of AgNO3 and TGA, adjusting the pH to 7 using NaOH, and adding a Na2S solution. The solution was kept at 25 ?C for 1 hour. For mixed composition samples, additional Na2S was added after holding for 1 hour. QDs were then dropped off using acetone and centrifuged to remove the reaction products before being re-dissolved in distilled water.

5：Data Analysis Methods:

The efficiency of energy transfer in hybrid associates was estimated using fitting experimental curves by the sum of several exponentials and determining the energy transfer efficiency between QDs with different sizes and ICG J-aggregates.
