“…In the first view Fig. 2a, the Y 3+ /Tm 3+ /Er 3+ ions are found in the center of bisdysphenoids sharing edges along the aaxis, while the V 5+ ions appear in a tetrahedral oxygen coordination along the c-axis, sharing opposite edges with the bisdysphenoid chains [4,36]. In the second view Fig.…”

“…In the FTIR of non-covered orthovanadate samples two bands are observed. The first one at 456 cm −1 can be assigned to the antisymmetric stretching vibration of the Y/Er 3+ -O and Y/Tm 3+ -O bonds, while the second broader and more intense band at 775 cm −1 is attributed to the antisymmetric stretching vibration of the V-O bonds in the VO 4 3groups [7,9,20,30,36]. A new strong band appears in the FTIR spectra of Y 0.9 Ln 0.1 VO 4 @SiO 2 at 1077 cm −1 with a small shoulder around 1202 cm −1 assignable to asymmetric stretching vibration modes of Si-O-Si and O-Si-O bonds, respectively [13,19,41].…”

“…3groups, respectively [9,30,36]. The strong band at 436 cm −1 can also be assigned to the asymmetric stretching vibration of the Y/Er 3+ -O and Y/Tm 3+ -O bonds, but coupled with both, the in-plane antisymmetric bending vibration of the Si-O bonds and the asymmetric stretching vibrations of the Fe-O bonds located in the octahedral sites [24].…”

“…A first band appears at 354 nm that can be assigned to charge transfer between V 5+ -O 2ions [7,8,36]. The VO 4 3groups acting as sensitizers absorb UV light photons and, once excited, transfer their energy to the Er 3+ ions located in the D 2d sites [13,37].…”

“…The VO 4 3groups acting as sensitizers absorb UV light photons and, once excited, transfer their energy to the Er 3+ ions located in the D 2d sites [13,37]. As a result, a new band appears at 450 nm [36]. This energy transfer causes electrons to populate the 4 F 7/2 level of the erbium ion, leading to non-radiative transits from this level to the 2 H 11/2 and 4 S 3/2 levels (see Fig.…”

Monodispersed microspheres play a major role in optical science and engineering, providing ideal building blocks for structural color materials. However, method towards high solid content (HSC) monodispersed microspheres has remained a key hurdle. Herein, we demonstrated a facile access to harvest monodispersed microspheres based on the emulsion polymerization mechanism, where anionic and nonionic surfactants were employed to achieve the electrostatic and steric dual‐stabilization balance in a synergistic manner. Monodispersed poly(styrene‐butyl acrylate‐methacrylic acid) (P(St‐BA‐MAA)) colloidal latex with 55 wt.% HSC was achieved, which shows an enhanced self‐assembly efficiency of 280% comparing with the low solid content (10 wt.%) latex. In addition, Ag‐coated colloidal photonic crystal (Ag@CPC) coating with near‐zero refractive index is achieved, presenting the characteristics of metamaterials. And a 11‐fold photoluminescence (PL) emission enhancement of CdSe@ZnS quantum dots (QDs) is realized by the Ag@CPC metamaterial coating. Taking advantage of high assembly efficiency, easily large‐scale film‐forming of the 55 wt.% HSC microspheres latex, we could easily produce robust Ag@CPC metamaterial coatings for passive cooling. The coating demonstrates excellent thermal insulation performance with theoretical cooling power of 30.4 W/m2, providing practical significance for scalable colloidal photonic crystal (CPC) architecture coatings in passive cooling.This article is protected by copyright.
