In the pursuit of new mid-IR laser gain materials, dysprosium-doped barium fluoride was evaluated for its potential laser emission in the 3-μm spectral region. Comprehensive spectroscopic characterization was performed, including absorption, fluores

The time-integrated and time-resolved photoluminescence (PL) of Cd0.3Zn0.7S0.06Se0.94/ZnS0.06Se0.94 single quantum wells (QW) have been studied at various temperatures. The time-resolved PL is obtained by sum frequency conversion technique with 300 f

By using the time-resolved photoluminescence technique, we have studied the temporal properties of the photoluminescence from several InGaAs/GaAs single quantum well samples at 77 K. The radiative recombination, the nonradiative recombination and the
