Synthesis, optical and thermal properties of novel Tb3+ doped RbCaF3 fluoroperovskite phosphors

Phosphors of pure and Tb3+ doped RbCaF3 were synthesized by the conventional solid state reaction method. The structure and morphology of the phosphors were characterized, using powder XRD and field emission scanning electron microscopy (FE-SEM). The presence of the functional groups was confirmed by using Fourier Transform Infra Red (FT-IR) spectral analysis. The absorption bands of Tb3+ ions with peaks at 220, 266 and 363 nm were observed in...
