ZnO has long been considered as a promising candidate material for diluted magnetic semiconductors, owing to its theoretically predicted and experimentally observed above-room-temperature ferromagnetism and long spin-coherence time. In this brief perspective, recent progress in ZnO diluted magnetic semiconductors is reviewed with particular focus on three topics: (1) spin coherence in ZnO; (2) free-carrier...
Structural and spectroscopic characterizations of the Ce3+/Tb3+(Mn2+) solely and Ce3+–Tb3+(Mn2+) doubly doped phosphate compound Ca9ZnLi(PO4)7 with β-Ca3(PO4)2 structure have been performed by powder X-ray diffraction and photoluminescence spectra measurements. The weak green emission from Tb3+ and red emission from Mn2+ are significantly enhanced by introduction of sensitizer Ce3+ ions due to an...
