AbstractPersistent spectral hole-burning (PSHB) phenomena of semiconductor quantum dots enable to perform the precise, high-resolution spectroscopy for the quantum dots of a certain size. We succeeded in the observation of the higher-excited states of excitons in CuCI quantum dots by means of the PSHB phenomena. Moreover, the exciton-state-splitting is observed and in agreement with the theoretical results on the assumption of platelet quantumdots.

The persistent spectral hole-burning (PSHB) phenomenon was observed in semiconductor quantum dots, CdSe , CuCl , and CuBr , embedded in glass and crystal. In inhomogeneously broadened exciton absorption spectra of these dots, the narrow bleaching hole and its associated structure are made by the narrowband laser excitation and are conserved for more than several hours at 2 K after the laser irradiation. The observation of the PSHB phenomenon in these four kinds of samples shows the generality of the phenomenon in semiconductor quantum dots and requires the existence of more than one ground-state configurations of the total system consisting of quantum dots and surrounding matrix. It means that not only the size distribution but also these ground-state configurations give inhomoge-neous broadening to semiconductor quantum dots. Thermally annealing and light-induced hole-filling phenomena were observed. Hole-burning and hole-filling mechanisms are discussed. Quantum dots consisting of 103–104 atoms behave like molecules or ions in matrix to give the PSHB phenomenon.
