• The fluorescence emission was investigated in single crystal specimens of CuCl at low temperatures. Strong emission lines of instrumentally limitted width are observed at wavelengths in the range of exciton absorption below 20°K. These lines are associated with recombination radiations from free and bound excitons with or without phonon cooperation, and they shift toward higher energy with increasing temperature as are observed in the exciton absorption bands. The average temperature coefficient of all the peak energy at low temperature is +2.5 × 10^<-4>eV/°K. From the temperature dependence of the emission intensity, the activation energies of the various processes are estimated; the ionization energy of the exciton is 0.16eV and the binding energies of the bound exciton complexes ranged between 0.03 and 0.007eV.
