UV-vis spectrum and luminescence spectra of the QC solution. (A) UV-vis spectrum of Ag7,8 QCs. Inset of (a) shows the corresponding luminescence spectrum collected at 273 K along with a photograph of the red emitting crude cluster solution under UV-lamp at 273 K. (b) Decreasing intensity of luminescence spectra of the QC solution with increase in time, after alumina powders were added. Photograph in the inset shows the decrease in the intensity of the color of the solution with time as clusters are loaded on alumina (under white light illumination).
