Abstract: The enhancement effect of dielectric dispersed double band emitting (ZnS+HgO):Cu,Mn(H) electroluminescent material has been investigated under the concurrent excitation of ac fields and 3650 Å UV-radiation. The emissions in yellow region were found to show relatively larger enhancement than that in case of green emission. The instantaneous behaviour of the individual peaks (green and yellow) was critically recorded and was observed that both the emissions isolately behave almost similarly and exhibit an exponential decay or rise before attaining the saturation value. The maximum enhancement is always found to be less than 4/3.
