Exoiton luminescence spectra in CuCl mioroorystals of a few nm in size embedded in glass are studied under selective excitation at the exoiton absorption bands homogeneously broadened by the size dietribution. The size-quantized exciton states are found to split into various components. From the analysis of the splitting on the basis of size-quantization of the exoiton transitional levels in the mioroorystals spheres, the z1,2 exoiton transitional mass, Luttinger parameters, and K-linear terms for z1,2 exciton are derived in thes compounds.
