Abstract
Research highlights: > The allowed 4f{sup 8}-4f{sup 7}5d transition of Tb{sup 3+} is beneficial for the emission of Tb{sup 3+} in obtained phosphate glass samples due to its high transmittance in the UV region and low covalency. > Increasing Tb{sup 3+} concentration in phosphate glass can greatly improve the emission intensity of Tb{sup 3+} at 541 nm, and the suitable concentration is 10 mol%. > Adding Ce{sup 3+} ions into Tb{sup 3+}-doped phosphate glass can greatly improve the emission intensity of Tb{sup 3+} at 541 nm, and the suitable concentration of Ce{sup 3+}/Tb{sup 3+} in phosphate glass is 2:10. > The luminescence intensity of Ce{sup 3+}/Tb{sup 3+}-codoped phosphate glass at 541 nm shows 8 times stronger than the commercial Bi{sub 4}Ge{sub 3}O{sub 12} (BGO) crystal with excited at X-ray. - Abstract: Phosphate glasses doped with different concentrations of Ce{sup 3+} and Tb{sup 3+} were prepared by high temperature melting method. Effects of Tb{sup 3+} concentration and sensitization of Ce{sup 3+} on photoluminescence and radio-luminescence properties of terbium doped phosphate glass have been investigated by absorption, excitation and emission spectroscopy. Results showed the phosphate glass exhibit high broad absorption band attribute to the allowed 4f{sup 8}-4f{sup 7}5d transition of Tb{sup 3+},
