The influence of hydrogenation on the luminescence characteristics of ZnO was investigated by low temperature photoluminescence (PL). Hydrogen was incorporated into the ZnO crystals from a remote dc plasma. It is found that hydrogen incorporation influences on the relative luminescence intensities of bound exci-tons
in particular the intensity of I

(3.363 eV) is enhanced and a emission peaked at 3.366 eV appears. Hydrogenated ZnO samples show a different temperature dependence of PL spectra compared with virgin ZnO samples.
