  • Abstract
    We report on the photocarrier generation mechanisms in TPD and TPD-AlQ3 blend. The spontaneous as well as the field induced carrier generation efficiency is enhanced in the blend. The spontaneous carrier generation efficiency, eta0 is 0.1% in TPD and it increases to 30% in the blend. Based on our results we demonstrate a visible-blind UV detector with a response of 30 mA/W using the TPD- AIQ3 blend as the active layer.
