Self-organizing structures of nanometer size are observed on the surface of CdZnTe crystal irradiated by strongly absorbed Nd:YAG laser radiation (LR) at intensities within 4 - 12 MW/cm2. The effect of exciton quantum confinement manifested by a shift to higher energies of the A0,X exciton band of the photoluminescent spectrum is present in structures of 10 – 15 nm in diameter at the top of nano-hills. A graded band gap structure with optical window is formed at the top of nano-hills.
