title = "Concentration quenching of tb3+ doped SiC:H and AlN thin films in photoluminescence and cathodoluminescence measurements",
abstract = "We present a systematic study of photo- and cathodoluminescence measurements in the visible of Terbium doped SiC:H and AlN thin films. The Terbium atomic concentrations vary from 0.9 to 10% for the SiC:H and from 0.8 to 6% for the AlN samples. For both materials the increase of the emission intensity with concentration and the subsequent quenching effect can be seen. The optimal concentration for the highest light emission is found. Photoluminescence excitation spectroscopy addresses the enhancement light emission mechanisms of the principal emission electronic transition of Terbium at ∼542 nm.",
