The (ZnS+HgO) binary phosphor system, activated with copper and manganese possess two distinct colour emissions (green and yellow) when excited by 3650A0 UV -radiation. The green emission due to copper dominates over yellow emission in photoluminescence. The temperature dependent studies of the photoluminescent output have also been made. It is found that the presence of hydrogen as cc-activator promotes the transfer of energy trom copper centers to manganese centers at high temperature and hence gives favorable response for photoluminescence.
