Abstract Tb3+-activated Sr2P2O7 phosphor samples were prepared via the co-precipitation route. The phase structure and vibrational characteristics of the synthesized phosphors were confirmed by X-ray diffraction and Fourier transform-infrared spectroscopy, respectively. The prepared phosphor exhibited green emission under VUV and UV excitation wavelengths of 147 nm, 172 nm, and 223 nm. The color-correlated temperature of the proposed phosphor suggested a cool greenish light. Based on our study results, we predict that these phosphors may be applied in green-emitting phosphors, optical display systems, white light-emitting diodes, and plasma display panels (PDP).
