“…Most of the experimental studies of optical phonons in QDs have been performed by Raman spectroscopy [1][2][3][4][5]. Quantum-size effect on optical phonons can also be seen by far-infrared (FIR) spectroscopy [6][7][8][9][10].…”

“…In our earlier papers we using far-infrared spectroscopy [6], Raman spectoscopy [7], and resonant Raman spectroscopy [8] to investigate structural and phonon properties of CdTe/ZnTe SAQD. By extending this study to phtoluminescence spectroscopy we expect to obtain electronic structure and get complete picture of optical properties of these samples.…”

We present photoluminescence (PL) measurements of two different, 3 monolayers and 12 monolayers (ml), CdTe self-assembled quantum dot (SAQD) samples. The spectra were recorded in the temperature range 20 K–300 K, with photoexcitation over the ZnTe barrier layer. PL spectra displayed two main emission bands. High-energy PL emission(E1)is ZnTe LO like phonon- (ωLO= 204.2 cm−1(3 ml),ωLO= 207.3 cm−1(12 ml)) assisted deexcitation. Dominant low-energy band(E2)presents the direct deexcitation to ground state of the CdTe quantum dots.
