Summary: The Dy3+, Mn4+: NaLaMgWO6 phosphors were successfully synthesized using solid-state reaction at 1150 ℃. XRD and SEM-EDS were used to analyze phase purity, while ICP was used to measure concentrations of various ions. The absorption and excited spectra showed that 390 nm was suitable for tunable yellow-red light excitation. Emission spectra with different doped concentrations ratios of Dy(3+) to Mn4+ demonstrated good tunable yellow-red emission performance when using 390-nm LED as the excitation source.
