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 …

The photoluminescence (PL) properties of Mn 4+-activated oxide phosphors are reviewed.
The phosphor materials considered here are almost all the oxide phosphors ever-reported …

Phosphor converted white light-emitting diodes (pc-WLEDs) are an alternative choice for
general lighting due to their superior features such as high efficiency, durability and …

Abstract Nowadays, Mn 4+-doped oxide phosphors have attracted more and more attentions
owing to their widespread applications in white LEDs, optical data storage and agricultural …

A review of the optical properties of Mn4+ ions in a number of host lattices is presented. As
an example, detailed crystal field calculations of the Mn4+ energy levels in Na2SiF6 and …

Mn4+ is known to activate red emission in many materials. However, the existing Mn4+
activated red phosphors have relatively long emission wavelengths and are therefore …

The measurement of high temperatures in oxides and oxide-based structures in practical
applications often presents challenges including steep thermal gradients, the presence of …

A new class of Mn4+ activated alkali-metal hexafluoride red phosphors are emerging for
white light-emitting diodes because of their sharp red line 2Eg→ 4A2g emissions (600–650 …

The aim of this paper is to report the optical properties of phosphor prepared by wet
chemical etching of Si wafers in a mixed solution. The luminescence centers of sharp red …

The feasibility of employing Mn4+-activated phosphors for bandshift luminesence
thermometry is demonstrated for the first time using Mn4+: Na4Mg (WO4) 3. Substitution of …
