Abstract:

The high degree of morphological and energetic disorder inherent to many nanosized materials places limitations on charge injection into and
transport rates through thin films of these materials. We demonstrate
electroluminescence achieved by local generation of charge that eliminates
the need for injection of charge carriers from the device electrodes. We
show electroluminescence from thin films of nanoscale materials that do
not support direct current excitation and suggest a mechanism for the
charge generation and electroluminescence that is consistent with our
time-averaged and time-resolved observations.
