Abstract	Currently, white light-emitting-diodes converted using Ce3+:Y3Al5O12 phosphor suffer from the shortage of red component and the easy aging of the organic silicone binder. Herein, a novel and non-rare-earth doped Mn4+:Y3Al5O12 red phosphor was synthesized by a traditional solid-state reaction. This phosphor can emit red luminescence attributed to Mn4+:2E → 4A2 spin-forbidden transition in the 600–700 nm spectral region and can be efficiently excited by both the commercially available near-ultraviolet and blue chips. Impressively, Mg2+, Ca2+, and Ge4+ dopants were found to be beneficial for enhancing Mn4+ luminescence, and the related mechanisms were systematically discussed. Furthermore, Mn4+:Y3Al5O12 embedded inorganic glass ceramic was successfully fabricated to replace the phosphor in organic silicone as the color converter, and a stacking geometric configuration by sequentially coupling a Ce3+:Y3Al5O12 glass ceramic and a Mn4+:Y3Al5O12 glass ceramic with an InGaN blue chip was designed to explore its possible application in warm white light-emitting diodes.
