TL;DR: An overview of recent studies on transition metal activated phosphors can be found in this article, including detailed synthesis routes (solid-state reaction and wet-chemical synthesis) and description of luminescence mechanisms and phosphors' behaviors; discuss their promising applications in white light-emitting diodes.

TL;DR: In this article, a new and efficient red phosphor BaGeF6:Mn4+ (denoted as BGFM) was reported by hydrothermally etching BaCO3 and GeO2 in HF solution with an optimized KMnO4 concentration.

TL;DR: In this article, Cs2TiF6:Mn4+ powder was successfully fabricated on a large scale through the cation exchange method using K2MnF6 as a Mn4+ source at ambient temperature.

TL;DR: In this article, red-emitting phosphors Na2XF6:Mn4+ (X = Si, Ge, Ti) were synthesized by a simple co-precipitation method and the crystal structure, morphology and composition of as-prepared phosphors were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive Xray spectrometer (EDS) and atomic absorption spectroscopy (AAS).

TL;DR: In this article, a Cs2ZrF6:Mn4+ red phosphor, a novel and efficient supplement for commercial Y3Al5O12:Ce3+ type white light-emitting diodes (WLEDs), is successfully fabricated on a large scale through a cation exchange method using K2MnF6 as the Mn4+ source at ambient temperature.
