Abstract

We showed a phase transformation from high temperature hexagonal phase to most stable monoclinic phase of SrAl₂O₄ by incorporating 20% of ZnO in ZnO and SrAl₂O₄ composite (Singh et al. 2014 Dalton Transactions). The composite with monoclinic phase further showed the intense near band edge emission and defect band emission corresponding to ZnO without any signature of SrAl₂O₄ in PL spectra. An energy band diagram responsible for defect band emission is proposed for the composites.
