The influence of laser light on fluorescence intensity and lifetime of CdSe/ZnS QDs and their complexes with organic molecules (PAN) in polymer matrix is discussed. The process of photo-induced dissociation of assemblies and self-fluorescence of QDs can occur in these films. Fluorescence intensity and lifetime dependence on laser power and laser energy are investigated. Possible application of QD/PAN assemblies as fluorescence nano-sensor is considered.
