A novel red-emitting Eu 3+ -doped Na 2 MgSiO 4 phosphor with high intensity of 5 D 0  →  7 F 4 transition

A broadband cyan-emitting Ca2LuZr2(AlO4)3:Ce3+ garnet phosphor for near-ultraviolet-pumped warm-white light-emitting diodes with an improved color rendering index

“…Furthermore, we also measured the IQEs of the as-prepared CLZA:x Ce 3+ (x = 1%, 2%, 4%, 6%, and 8%) phosphors using the integrating sphere method, and the results are listed in Table 2. The corresponding values of IQEs for the CLZA:x Ce 3+ phosphors were calculated by using the following formula: 67,69,70…”

Defect-induced zero thermal quenching of a bright red-emitting nonlinear optical material

“…This phenomenon can be explained by a highly polarized chemical environment and ligand polyhedral distortion. [44][45][46] The high electronegativity of O 2À and P 3+ causes this highly polarized chemical environment. Meanwhile, when Cs + is replaced by Eu 3+ , the difference in the two ionic radii makes the crystal structure distorted.…”

Color‐Tunable Eu3+, Eu2+‐Activated CaSiO3 Nano Phosphor Extract from Agricultural‐Recycling‐Food‐Waste Materials for Display Applications

“…This means that radiation-less energy transfer between Eu 3þ ions is extremely unlikely and unaffected by Eu 3þ ion concentration. [46,47] 3.6. PL Spectra of Eu 2þ -Doped CaSiO 3 Nano Phosphor Figure 11 and 12 show the PLE and PL spectra of Eu 2þ -CaSiO 3 prepared in a reduction atmosphere at different excitation wavelengths.…”
