Abstract :
We have successfully prepared the luminescent material of Sr2(P2O7):Ce3+, Tb3+ by the method of the chemical co-precipitation. The phase structure, surface morphology and fluorescence properties were investigated by the scanning electronic microscopy (SEM), X-ray diffraction (XRD), and photoluminescence (PL). It showed that the luminescent material is composed of the pure Sr2(P2O7) phase, and there no phases of rare earth phosphate appeared. The SEM micrographs showed uniform particles with good crystallinity of luminescent material synthesized at 1100°C. PL spectrum showed the luminescent material fluorescence effect best with nSr: nTb= 100: 1, nTb: nCe=2:3, sintering at 1100°C, the optimal heat preservation time was 3h.
