| Abstract | A green-emitting phosphor CaMoO4 co-dopped by Tb3+ and alkali metals ions (R+) was fabricated by solid-state method. X-ray powder diffraction (XRD) analysis revealed that pure CaMoO4 was obtained. The excitation and emission spectra indicated that the phosphor could be well excited by ultraviolet light (375 nm) or blue light (488 nm) and emit green light at about 548 nm. The results showed that incorporation R+ (Li+, Na+ and K+) of into CaMoO4:Tb phosphor could lead to a remarkable increase of photoluminescence or X-ray excited luminescence. It was found that the luminescent intensity depended on the doped concentration. The phosphor doped with 5 mol% Tb3+ and 5 mol% Na+ showed the highest |
