【Abstract】 Efficient ZnS:Er alternating current thin film electroluminescent devices(ACTFELDs) have been fabricated based on the mechanism that the energy gain and excitation efficiency of charge carriers can be increased by means of barrier layer tunnelling along with the modification of the conventional structure.The experimental results indicate that the multi-barrier layer devices offer a higher threshold voltage and greater electroluminescence brightness.更多还原
