Time characteristics of the luminescence of Al-ZnS:Mn-InxOy structures excited by a single voltage pulse

We have studied and compared oscillograms of the brightness and the reactive current during the excitation of Al-ZnS:Mn-InxOy structures by a single voltage pulse. Disagreement of the results obtained with solutions of the kinetic equations which describe direct collisional excitation of the activator by hot electrons was observed. Based on the results found and analysis of data in the literature it is proposed that there are excitations which transmit the energy to the manganese centers.
