摘要：
A series of luminescent emission-tunable phosphors Ca12Al14O32F2: xEu were synthesized by combustion method. X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM) and photoluminescence spectra (PL) were used to characterize the phosphors. The effects of combustion temperature, ammonium fluoride, urea, boric acid and co-activator Eu3+-Eu2+ on the luminescent properties of the phosphors were also studied. The results show that the emission color of the prepared phosphors can be tuned appropriately from orange red to blue by adjusting the synthesis condition due to the coexistence of Eu3+ and Eu2+. © 2016, Science Press.
