Photoluminescent properties of Sm³⁺/ Dy³⁺ single and co-doped SrZrO₃ perovskites, prepared through conventional solid state ceramic route method were investigated. X-ray diffraction studies confirmed the orthorhombic (Pnma) perovskite structure of the calcined samples. Dy³⁺doped SrZrO₃ systems showed blue emission at 482 nm and yellow emission at 574 nm due to the transition between ⁴F_9/2-⁶H_15/2 and ⁴F_9/2-⁶H_13/2 levels respectively while Sm³⁺ doped SrZrO₃ systems shows red emissions at around 567 nm, 603 and 646 nm that respectively corresponds to the ⁴G_5/2 → ⁶H_5/2, ⁴G_5/2 → ⁶H_7/2 and ⁴G_5/2 → ⁶H_9/2 transitions of Sm³⁺. Sm³⁺/ Dy³⁺ co-doped SrZrO₃ systems shows two different emissions for excitations at 350 nm and 407 nm. Near white light emission was achieved for the SrZr_0.9Sm_0.025Dy_0.075O₃, SrZr_0.9Sm_0.05Dy_0.05O₃ andSrZr_0.9Sm_0.075Dy_0.025O₃ systems at 354 nm excitation with CIE colour co-ordinates (0.3792, 0.3849), (0.3813, 0.3853) and (0.3786, 0.3851) respectively.
