In this paper, we studied a doping layer in ALq3 single layer by transient-electrolumine scence(EL).
T-EL was measured as the pulse width was varied in fixed voltage(7V). When the voltage pulse was turned off we observer the ELspike the hight of the ELspike was increase as the pulse width was increased. The trapped charges in dopant molecules were detrapped after the voltage off and recombined to make the ELspike.
