Abstract
We report on the observation of the doubly resonant secondary emission involving 2s- and 1s-exciton states. The resonance conditions have be en realized in CdTe/Cd1-xMnxTe quantum-well structures by magnetic-fie ld tuning of the 2s-1s energy spacing to the LO-phonon energy. Theoret ical analysis shows the doubly resonant process to be indirect, with h ot 1s excitons acting as intermediate states. It is concluded that-the resonance width of 2.6 meV gives the 2s-exciton homogeneous linewidth governed by elastic scattering into the hot 1s-exciton states.
