Abstract
•Europium doped ZnO ceramic exhibits photo-luminescence.•Semiconductor hetro-junction was prepared.•ZnO:Eu3+|CuSCN hetero-junction emits red light under reverse bias.
Eu3+ ions were bonded to ZnO ceramic via organic ligand. Surface bonded Eu3+ ions were exhibited specific luminescence bands due to electron transitions between f–f intra-configurationally transitions. Further enhancement of luminescence bands was observed by attaching selected oligomers to Eu3+ ions. A hetero-junction was prepared by depositing copper-thiocyanate on Eu3+ ions bonded ZnO ceramic. Red light emission was observed from surface bonded Eu3+ ions in ZnO:Eu3+|CuSCN hetero-junction under reverse bias.
