The severe urban heat island effect emphasizes the heightened importance of reducing building energy consumption. Cool pigments with higher near-infrared reflectivity contribute to overall coating performance building. In this work, a novel intense blue pigment superior infrared reflectance based on Ni-doped Zn2SiO4 was successfully synthesized via simple solid-state method. crystal structure, oxidation states, and optical properties are analyzed. state Ni confirmed be +2 using magnetic...
Blue pigments and blue glazes play crucial roles in our daily life. Ongoing research into aims at environmentally friendly compositions with a lower cost. In this work, Co-doped BaAl2Si2O8 were synthesized by solid-state method. The color of the is due to 4A2(4F) → 4T1(4P) transitions allowed doped Co2+ tetrahedral coordination structure. exhibit excellent stability under both acidic alkaline conditions. When combined transparent glazes, BaAl2–xCoxSi2O8 demonstrates satisfied compatibility,...
Mg2.2-xCoxTiO4 (0≤x≤0.6) and Mg2.2-xCrxTiO4 solid solutions with spinel structure were successfully synthesized by solid-phase reaction. Excess MgO was added to achieve the single phase of compounds. The transition metal ions Co/Cr tune colors Mg2TiO4 intense blue green, respectively. root observed color is attributed 4A2 (F) → 4T1 (P) Co2+ in tetrahedral coordination. In Cr doped Mg2TiO4, exists a mixed oxidation states +3 +6. green as-synthesized charge mass transfer Cr3+ at 420 nm 4T2 3d...

In recent years, NIR-II-type fluorophores with emission wavelengths within the 1000-1700 nm range have garnered widespread attention in field of bioimaging due to their high tissue penetration ability. Here, Mn-doped BaAl2O4, Ba3Al2O6, and Ba7Al2O10 phoshorescence were synthesized by solid-phase or liquid-phase methods. Confirmed XPS EDS analysis, Mn is found uniformly distributed structure valence state +5. The optimal doping concentration Mn5+ three matrices was analyzed PLE PL...
Abstract This study is focused on the synthesis and luminescent properties of novel alkaline silicate phosphors. Conventional solid state reaction method adopted to synthesize earth element-activated phosphors co-doping To Ba3MgSi2O8 host, we discuss effect different flux, flux concentration, firing temperture.In doping process temperture, concentration atmosphere observed.Finally try make a EL device with phosphor made.When add 2wt% H3BO3 fireing temperture 1250°C, will have good emission...
