It was shown that the transition to low temperature, accompanied by a decrease in the efficacy of non\u2010radiative processes, manifests itself (depending on the solvent) in a 3\u2010 to 7\u2010fold increase in the fluorescence quantum yield and fluorescence decay time, a sharp decrease in the Stokes shift, and the appearance of a vibrational structure in the fluorescence and fluorescence excitation spectra of curcumin. Rigid glass matrices were used to record phosphorescence, the attribution of which to curcumin was confirmed for the first time by the correspondence of its excitation spectrum to the fluorescence excitation spectrum at 77\u2009K. The phosphorescence maximum of curcumin was shown to be located at \u2009=\u2009635\u2009nm, which differs significantly from the data (=\u2009730\u2009nm) of the most cited work on curcumin photonics. The quantum yield of curcumin phosphorescence and its decay times were estimated for each solvent. By monitoring the luminescence of curcumin\u2010sensitized singlet oxygen generation in the 1270\u2009nm region, its quantum yield (\n                    <jats:italic>\u03c6<\/jats:italic>\n                    <jats:sub>\u0394<\/jats:sub>\n                    ) was determined in a number of organic solvents.
