dc.description.abstract	The photoluminescence (PL), transmittance and IR reflectance spectra were investigated for ZnO single crystals grown by the HCl chemical vapor transport technique. Electrical parameters were also calculated from the Hall effect measurements. The characteristics of ZnO:HCl crystals basically depend on the centers caused by the chlorine impurity. The deep acceptors attributed to Cl-VZn centers with activation energy of 640±60 meV influence on the PL and optical properties. Cl donors cause luminescent and electric properties of high conductive crystals; they have activation energy of 115±15 meV according to PL spectra and 67±18 meV according to the electrical properties. Obtained crystals are characterized also by a strong optical absorption in the near-IR spectral range.	en_US
