摘要：
Considering the positive implication of designing singular emitting phosphor in the area of bioimaging and solid state lighting, this work reports on singular orange emission from Zn2SnO4:Eu3+ (ZSOE) phosphor. The studies showed that ZSOE is stabilized in inverse spinel structure with Eu getting stabilized in octahedral Zn sites with orthorhombic symmetry and D-2h point group leading to very intense orange emission with negligible red component. Undoped Zn2SnO4 (ZSO) on ultraviolet irradiation depicted defect induced blue emission due to synergetic effect of F-centers and vacancy clusters. (C) 2020 Elsevier B.V. All rights reserved.
