Abstract

An investigation of the time-resolved photoluminescence decay in glow-dischargingly deposited hydrogenated amorphous carbon is presented, the dependence upon substrat temperature, emission energy, and excitation energy has been investigated. Our measurements suggest the exciton recombination rather than the pair process. The photoluminescence decay time decreases with increasing substrat temperature, as result of enhancing nonradiative recombination. Comparisons with hydrogenated amorphous silicon are also made.
