We report the photoluminescence (PL) observation of extremely sharp zero-phonon lines originating from transitions of Mn[sup 2+] and Cr[sup 3+] ions embedded into MgO matrix of nanoscale (nanocrystals and films). The excellent performance of PL compared to that from quantum dots makes our finding attractive for applications. © 2003 American Institute of Physics.

    A microcavity structure, containing self-assembled InGaAs quantum dots, is studied by angle-resolved photoluminescence (PL) spectroscopy. A doublet with the splitting energy of 0.5-1.5 nm appears when the detection angle is larger than 35°. This doublet is identified as mode splitting (not...

    Photo-oxidation of densely packed monolayer of CdSe quantum dots (QDs) was studied by time-resolved photoluminescence (PL) spectroscopy. Electrons yielded in QDs by the strong laser-pulse irradiation can assist the oxidation of CdSe QDs. Such rapid photo-oxidation does not introduce more...

    Taking into account the tetrahedral shape of a quantum dot quantum well (QDQW) when describing excitonic states, phonon modes and the exciton-phonon interaction in the structure, we obtain a quantitative interpretation of the photoluminescence (PL) spectrum of a single CdS/HgS/CdS QDQW within a...
