AbstractAn experimental assessment of europium doped Al2O3spherical phosphors has been conducted, in conjunction with a controllable morphology via one-pot hydrothermal synthesis route and typical red light emission. The most important synthesis step of spheres is utilizing of glucose as structuring additive, followed by a subsequent calcination process in a range of 600–1300 °C. It was found that the final products Al2O3:Eu3+exhibited a micro-spherical structure. SEM images indicate that the spheres consist of cross-linked sheets at lower calcination temperatures or coral-like subunits at higher temperatures. XRD patterns show that the adequate calcination temperature can guarantee a well-crystallized Al2O3phase formation. Furthermore, under excitation of a xenon lamp (λex= 392 nm), the Al2O3:Eu3+phosphors exhibit a bright red emission. All results of this research can also contribute to a simple synthesis route of metal oxide based phosphors with spherical morphology and lower temperature conditions. © 2017 Elsevier B.V.
