Abstract:
We have observed a significant increase in the intensity of photoluminescence (PL) from polyvinylpyrrolidone-stabilized suspensions of PbS quantum dots upon irradiation in a broad spectral range and subsequent storage in the dark at room temperature. It is also established that analogous changes are observed in dense polymer coatings deposited on glass substrates from these suspensions. It is suggested that the observed changes in PL intensity are related to the evolution of the clusters of PbS quantum dots.
