Mn 4+-activated phosphors are a new class of non-rare earth phosphors and are alternative
to commercial Eu 2+-activated nitride/oxynitride phosphors with growing interest in various …

In this review article, Mn applications have been divided into three parts. We provide an
overview of recent progress in developing Mn4+ doped red phosphors for promising …

Photoluminescence originated from doped activators in the solid state materials usually
faces the challenge of concentration quenching, restricting the further increase of …

Red-emitting phosphors composed of Mn 4+-activated fluorides have attracted considerable
interest for their applications in warm white light-emitting diodes (WLEDs). However, in …

Ba1. 8–x Sr x SiO4: 0.1 Ce3+, 0.1 Na+ (x= 0–1.8) phosphors were prepared by a high-
temperature solid-state reaction. The emission peaks of Ba1. 8–x Sr x SiO4: 0.1 Ce3+, 0.1 …

Poor water resistance and nongreen synthesis remain great challenges for commercial
narrow red-emitting phosphor A2MF6: Mn4+ (A= alkali metal ion; M= Si, Ge, Ti) for solid …

Due to the unique narrow-band red emission and broadband blue light excitation, as well as
milder synthesis conditions, Mn4+ ion activated fluoride red phosphors show great promise …

A new generation of red phosphors of complex fluoride matrices activated with Mn4+ has
gained a broad interest in getting high color quality and low color temperature of solid-state …

Energy migration (energy transfer among identical luminescence centers) is always thought
to be related to the concentration quenching in luminescence materials. However, the novel …

Narrow‐band red‐emitting fluoride phosphors play a crucial role in lighting and backlight
displays, whereas the stability issue is a major challenge. Here, highly stable K2SiF6: Mn4+ …
