Transparent conducting oxides are popular materials for electrostatically tunable metasurfaces due to their voltage-tunable plasma frequencies along with epsilon-near-zero dispersion points that fall in the infrared. Ion-gel-gated films of the transparent conductor perovskite BaSnO3 show large, low power changes in carrier density and electron mobility under electron accumulation. However, the corresponding optical changes in ion-gel-gated BaSnO3 are unknown. Here, we study near-infrared refractive index modulation in ion-gel-gated La-doped BSO for active metasurfaces through optical modeling rooted in realistic material data. Near-infrared spectroscopic ellipsometry of as-grown n-type BaSnO3 films establishes Drude optical parameters vs carrier density. We then ion-gel-gate BaSnO3 into electron accumulation, where in situ Hall effect measurements and subsequent electrostatic modeling reveal a ∼4-fold carrier density enhancement near the film surface despite high initial doping of >1020 cm–3. We map doping-dependent Drude parameters onto the measured carrier density modulation, enabling us to model the voltage-dependent near-infrared refractive index changes in BaSnO3, which exceed unity at the 1550 nm telecom band. Finally, our voltage-dependent refractive index data enable simulations of plasmonic metasurfaces with BaSnO3, which we design to achieve reconfigurable beam steering at near-telecom wavelengths. These findings frame ion-gel gated BaSnO3 as a promising material for reconfigurable infrared metasurfaces and motivate the design of similar tunable photonic devices based on its large refractive index changes.","PeriodicalId":29803,"journal":{"name":"ACS Applied Optical Materials","volume":"3 5","pages":"1153–1161 1153–1161"},"PeriodicalIF":0.0,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144114527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We optimized the synthesis parameters to modulate sol properties and thereby achieved a high-quality MOF film with a smooth surface (Rms ∼ 24 nm) and exceptional transparency exceeding 90% within the visible range. By repeating dip-coating, the desired thickness of large-area MOF films (2.5 × 2.5 cm2) can be tuned within the wide range of 38 nm to 2.2 μm. Finally, we achieved confined growth of MAPbBr3 NCs within the UiO-66-NH2 films and investigated the growth mechanism, demonstrating the potential of UiO-66-NH2 for functional applications. These findings suggest that the resulting UiO-66-NH2 films hold great promise for applications in photonic devices such as light-emitting diodes, lasers, and optical sensors.","PeriodicalId":29803,"journal":{"name":"ACS Applied Optical Materials","volume":"3 5","pages":"1088–1096 1088–1096"},"PeriodicalIF":0.0,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144114562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the other hand, structural color photonic pigments, which derive their color from reflectance of light rather than absorption, can be made from sustainable, inexpensive materials and are nonfading. Supraparticles, which are spherical assemblies of colloidal particles, reflect light of a certain wavelength, depending on the particle size of the building blocks. In this work, we synthesized building blocks with an optimized scattering-to-absorption ratio by employing a polydopamine coating and created supraparticles via bulk emulsification and osmotic extraction. We evaluated the optical performance of water-based paint containing supraparticles of different sizes, polydispersities, structures, and degrees of absorption. We found that a larger size and higher polydispersity of the supraparticles led to paints with a wider reflection peak. The degree of crystallinity of the supraparticles, which decreased for polydopamine-coated compared to uncoated particles and was tuned via the osmotic pressure difference between droplets, had a comparatively smaller impact on the optical performance. Additionally, the scattering-to-absorption ratio of the building blocks allowed us to precisely tune the color in the paints. After these optimizations, the photonic supraparticle paints were used to paint several drawings to showcase their applicability, providing guidelines for high-quality photonic supraparticle pigments in water-based paints.","PeriodicalId":29803,"journal":{"name":"ACS Applied Optical Materials","volume":"3 4","pages":"1025–1035 1025–1035"},"PeriodicalIF":0.0,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsaom.5c00080","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143867304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, three different π-rich aromatic dianhydrides are employed to introduce molecularly quantized trap states into the conduction band of C3N4 to facilitate efficient charge separation, and to promote an enhanced photocatalytic CO2 reduction response. These modified C3N4 materials have been characterized structurally and spectroscopically for use as a support for Co-based SACs. In photocatalytic CO2 reduction studies, the Co SAC on naphthalene dianhydride-doped C3N4 exhibited the highest activity and selectivity toward CO production among the Co SACs tested in this work. The observed improvement in photocatalytic CO2-to-CO conversion activity correlates with trends in photoinduced charge separation, as revealed by photoluminescence spectroscopy.","PeriodicalId":29803,"journal":{"name":"ACS Applied Optical Materials","volume":"3 4","pages":"881–888 881–888"},"PeriodicalIF":0.0,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143867571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
