Аннотация:<jats:title>Abstract</jats:title><jats:p>During pursuing high color rendering index for full-color-emitting phosphor, low quantum efficiency (QE) is usually accompanying. We intend to elevate the luminescence efficiency when realizing a solar-like spectra distribution, by constructing apatite structure oxynitride, inheriting high covalence and rigidity from oxynitride, and suitable multiple cation sites from oxyapatite compounds. Full-color-emitting apatite structure oxynitride phosphor (Mg,Y)<jats:sub>5</jats:sub>Si<jats:sub>3</jats:sub>(O,N)<jats:sub>13</jats:sub>:Ce<jats:sup>3+</jats:sup>,Mn<jats:sup>2+</jats:sup> has been prepared, and the crystal sites’ occupancies of activators in this host were favorable for white emission.

The fabricated white light-emitting diode lamp demonstrated the distinctive overall performance of QE and chromaticity properties (<jats:italic>R</jats:italic><jats:sub>a</jats:sub> and <jats:italic>R</jats:italic><jats:sub>9</jats:sub>). Furthermore, correlated color temperature is tunable from cool nature to warm white. The obtained lamp possesses the feature of less blue light hazard and high saturation of red degree, compared with the commercial YAG-based lamp.</jats:p>
