Abstract: The advantages of dye-doped polymer matrices over polymers and dyes, separately, are analyzed. The effects of the polymer nature and chemical constitution of organic dyes on the spectral and luminescent properties of these matrices are discussed. The processes of dye aggregation in polymers are characterized, and their influence on the photophysical properties and photochemical stability of dye-doped nonphotoconducting and photoconducting polymers is discussed. The different approaches for the struggle with dye aggregation in polymers are offered. The main paths of energy degradation of electronic excitation in such materials are analyzed. The prospects for the applications of dye-doped polymer materials as passive Q-switches of solid-state lasers, active laser media (ALM), luminescent solar concentrator (LSCs), photovoltaic cells, and electroluminescent (EL) emitters are demonstrated.
