Persistent spectral hole burning (PSHB) spectroscopy was utilized to investigate excited state excitons confined in CuCl quantum dots embedded in NaCl crystals. In the PSHB spectra of CuCl quantum dots, a resonantly burned hole and lower energy satellite holes were observed. These satellite holes are thought to originate from hole burning of the ground state excitons which results from site-selective excitation of excited state excitons confined in CuCl quantum dots. Relations between energy positions of the resonantly burned hole and that of each satellite hole are explained well in terms of the simple concept of a particle in a quantum cube with infinitely high potential barriers. Spectral profiles of the ground state excitons and the first excited state excitons confined in CuCl quantum dots were obtained. The Z3 exciton luminescence spectrum showed that the excited state excitons are in a majority in the higher energy region of the Z3 exciton absorption band.
