Experimental Test of the Principle of Microscopic Reversibility in Photoluminescence Decay Kinetics

The similarity of photoluminescence decay kinetic curves at the inversion of the wavelengths of excitation and detection of photoluminescence has been experimentally demonstrated. In this case, if the direct process is Stokes photoluminescence, the reverse process inevitably falls in the anti-Stokes region of the spectrum. The experiments have been performed with colloidal solutions of InP/ZnS quantum dot nanoclusters that do not satisfy the Vavilov law of the independence of luminescent characteristics of a luminophore of the pump light wavelength.
