Ba2SiO4−δN2/3δ:Eu2+ (BSON:Eu2+) materials with different N3− contents were successfully prepared and characterized. Rietveld refinements showed that N3− ions were partially substituted for the O2− ions in the SiO4-tetrahedra because the bon

Finding new phosphors through an efficient method is important in terms of saving time and cost related to the development of phosphor materials. The ability to identify new phosphors through preliminary simulations by calculations prior to the actua

Recently, a novel host, K3SiF7, for Mn4+-activated phosphors was discovered and it was revealed that Mn4+-doped K3SiF7 has an advantage in decay time compared with the most widely used Mn4+-doped K2SiF6. Here, we developed an organic solvent-assisted

A narrow-band red emission is a seminal issue for establishing the color-rendering index and color gamut of phosphor-converted white light emitting diode (pc-WLED) applications. In this regard, Mn4+-activated K2SiF6 phosphors (referred to as K216) ha

Blue-emitting Ca2–xMgxSiO4:Ce (0.0 ≤ x ≤ 1.0) phosphors were successfully synthesized and characterized. Rietveld refinement revealed that four main phases exist within the solid-solution range of CaO-MgO-SiO2, namely, β-Ca2SiO4 (Mg (x) = 0.0)

Phosphors that exhibit a narrow red emission are particularly interesting due to the advantage of providing a more extensive color gamut and better rendering in LED applications such as displays and solid-state lighting. Although some Eu2+-activated

Eu-doped CaAlSiN3 (CASN) is widely utilized as an efficient red phosphor; however, the high price of rare-earth metals has driven efforts toward finding non-rare-earth metal dopants. This paper reports first-principles calculations based on density f
