Optical absorption spectra of the direct exciton of TlCl and TlBr micro-crystals are measured in evaporated thin films at 5.0K. The energy of the direct exciton bands shift to higher energy with decreasign micro-crystal size. The lower component of the doublet of the exciton in TlCl decreases its intensity with decreasing micro-crystal size. The experimental results are discussed with the quantum-size effect on the exciton states and on the electron-hole exchange interaction in an exciton.
