In this work, the Photoluminescent (PL) and Photocatalytic (PC) properties of Cr³⁺ doped Zn₂TiO₄ nanoparticles are presented. Zn₂TiO₄: Cr³⁺ phosphors were prepared from by combustion route and the formation of Zn₂TiO₄was confirmed by Powder X-ray diffraction (PXRD), morphology and optical studies were analyzed by Field Emission Scanning Electron Microscopy (FESEM) and Diffuse Reflectance Spectroscopic (DRS) techniques. Photoluminescence spectra exhibit the emissions in the orange-red region ⁴T₂→⁴A₂ and a sharp, high-intensity peak at 674 nm due to the ²E→⁴A₂ and ²E→⁴A₂ transitions are the corresponding transitions for orange-red emission. Further, the prepared material was used to evaluate the dye degradation and exhibits excellent photocatalytic performance on fast orange-red dye. All the obtained results indicate that prepared Zn₂TiO₄ is a promising material for display, solid state lighting, and catalytic applications.
