Carbothermal synthesis of CaAlSiN3:Eu2+ red-emitting phosphors and the photoluminescent properties

“…ions are accommodated in cavities formed by (Al/Si) 6 N 18 rings with five N -3 coordination anions. It is found that Al/Si disorderly occupies the 8b site with a ratio of about 1/2 with a more appropriate formula CaAl 1-4d/ 3 Si 1?d N 3 (d = 0.3-0.4) instead of 1/1 proposed for an ideal CaAlSiN 3 , probably due to the incomplete reaction resulting in a significantly lower Al solubility in CaAlSiN 3 [20]. Thus, a tiny amount of AlN impurity is detected for CaAlSiN 3 -based phosphor samples.…”

“…yellow emitting phosphor was reported by Zhang et al [17] with carbothermal route using SrCO 3 and CeO 2 as raw materials. Comparing with other synthetic routes (such as, solid-state reaction, ammonothermal method and combustion technique) [4,18,19], carbothermal synthesis was identified as a facile route for preparation of nitrides phosphors by considering of its outstanding advantages in relative low reaction temperature (1400-1600°C), cheap raw materials (oxides or carbonates, SrCO 3 , CaCO 3 , Eu 2 O 3 ) and simple processing [20][21][22]. As one of significant nitride phosphor, CaAlSiN 3 :Eu 2?…”

Bane to boon: tailored defect induced bright red luminescence from cuprous iodide nanophosphors for on-demand rare-earth-free energy-saving lighting applications

“…On the other hand, a smaller particle size is also needed to realize higher resolution for display technology. 30,31 Keeping these points in mind, a careful survey regarding the PL properties of previously reported red nanophosphors is presented in Table 1. From the table, it can be clearly perceived that the emission characteristics of this CuI nanophosphor are not only equally comparable with the red nanophosphors already reported in the literature but also it serves multifold advantages such as being ecofriendly, non-toxic and stable.…”

Upconversion Nanoparticle-Based Nanocomposites

“…When inorganic rare earth luminescent nanoparticles are dispersed into polymer hybrid precursors, various 1D rare earth luminescent materials with multiform morphologies such as fiber, wire, belt, and tube can be achieved readily via the electrospinning route, which has potential applications in fluorescent lamps and color displays [71][72][73]. Lin's group has demonstrated that the electrospinning route is also an effective approach to prepare UCNP-mSiO 2 multi-functional materials, which can act as promising drug carriers for biomedical applications [74][75][76][77][78][79].…”
