Tartarate precursors of CaAl2O4, CaAl2O4:Tb3+, SrAl2O4, SrAl2O4:Tb3+.
The hexagonal CaAl2O4 and monoclinic SrAl2O4 single phases were confirmed by XRD.
The average crystallite size was ∼64 nm for CaAl2O4 and ∼46 nm for SrAl2O4.
Photoluminescence and thermoluminescence properties are related to the Tb3+-doping.
