- 論文の詳細を見る
In addition to the zero phonon resonance line of the luminescence due to freeexcitons in the lowest energy band, a few very weak luminescence lines assistedby LO phonons are observed in Kl and Rbl crystals. The shapes of the zerophonon and LO phonon assisted luminescence lines are studied under the UVlight excitation in the first exciton absorption band at a temperature range between80 K and 3 K. The zero phonon and LO phonon lines in Kl and the zero phononline in Rbl are of symmetric Lorentzian shapes below 10 K. They become asym-metric shapes (nearly Maxwellian) above 10 K. Half-widths of the zero phononand LO phonon lines in both crystals are about 1.4 meV and 4 -5 meV at 3 K,respectively.
