Synthesis and Luminescence Properties of Green-emitting Phosphor CaSc2O4:Ce3+
文献摘要：
Using CaCO3, Sc2O3, and CeO2 as raw materials, we prepared the CaSc2O4:Ce3+ green phosphors for white light LEDs via a high-temperature solid-phase method in a reducing atmosphere. X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), fluorescence spectroscopy and other means were used to characterize the phase structure, apparent morphology, and photoluminescence properties of the product. CaSc2O4 was synthesized under a reducing atmosphere (95％ N2+5％ H2) at 1400 ℃ for 4 hours. Upon excitation with a blue light (450 nm wavelength), CaSc2O4:Ce3+ displays a broadband green emission peak at 525 nm. The color coordinates of CaSc2O4:7％ Ce3+ emission peak are (0.3712, 0.5940), and the product morphology is 1 μm granular. Hence, it acts as a green phosphor suitable for white LEDs that can be excited by blue light.
