N2 - We investigated two-photon excitation spectra of confined excitons of CuCl nanocrystals embedded in a NaCl matrix. The spectra exhibit a sharp increase that is attributed to transitions into higher Coulombic states (Formula presented) of the confined excitons, and its position shifts to a higher energy side with decreasing crystal size. We also discuss the difference in peak positions between one- and two-photon absorption spectra in the presence of a broad inhomogeneous width due to the size distribution.
