Abstract:

We synthesized a kind of green phosphor, NaBaPOM4:Tb3+, by the high temperature solid-state method, and investigated its luminescent characteristics. NaBaPO4:Tb3+ has several emission peaks, and these are located at 437, 490, 543, 587, and 624 nm, which correspond to the 5D37D4 and 5D47FJ=6. 5, 4, 3 transitions of Tb3+, respectively. The main peak is at 543 nm. The excitation spectrum (monitored at an emission wavelength of 543 nm) consists of several bands, and the main peak is located at 380 nm. The effect of amount of Tb3+ doping content, the compensators (Li+, Na+, K+, or Cl-), and the sensitizer activator Ce3+ on the emission intensity of the NaBaPOM4:Tb3+ phosphor were also studied. The results show that the emission intensity can be controlled by the above factors, and the intensity can be enhanced by selecting the prime optimum conditions.
