Abstract To explore suitable single-phase white emission phosphors for warm white light emitting diodes, a series of novel phosphors Na3MgZr(PO4)3:xDy3+ (0≤ x≤ 0.03) is prepared, and their phase purities as well as photoluminescence properties are discussed in depth via x-ray diffraction structure refinement and photoluminescence spectrum measurement. The electronic structure properties of the Na3MgZr(PO4)3 host are calculated. The results reveal that Na3MgZr(PO4)3 possesses a direct band gap with a band gap value of 4.917 eV. The obtained Na3MgZr(PO4)3:Dy3+ phosphors are all well crystallized in trigonal structure with space group R3c, which has strong absorption around 365 nm and can generate warm white light emissions peaking at 487, 576, and 673 nm upon ultraviolet excitation, which are attributed to the transitions from 4F9/2 to 6H15/2, 6H13/2, and 6H11/2 of Dy3+ ions, respectively. The optimal doping content, critical distance, decay time, and Commission International de L'Eclairage (CIE) chromaticity coordinates are investigated in Dy3+ ion-doped Na3MgZr(PO4)3. The thermal quenching analysis shows that Na3MgZr(PO4)3:Dy3+ has a good thermal stability, and the thermal activation energy is calculated. The performances of Na3MgZr(PO4)3:Dy3+ make it a potential single-phase white emission phosphor for warm white light emitting diode.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
