IR Absorption of OH and OD Centres and OH/OH, OD/OD, and OH/OD Complexes in Cu‐Doped ZnO Single Crystals

With ZnO:Cu:H, ZnO:Cu:D, and ZnO:Cu:H:D IR‐active absorption line spectra composed of 20 absorption bands are observed. Regarding the values of the absorption coefficients one of the 20 absorption bands is prominent (“main peak”), 18 absorption bands lie on the high energy side of the main peak (“side bands”). Measurements with the main peaks and the side bands are represented.
