Broadband and tunable near-infrared emission of CaMg2Al16O27:Fe3+ with multi-site engineering

Near-infrared (NIR) light has low scattering coefficient, strong penetration capability, and selective absorption by specific molecular features, causing that the developing broadband and high-efficiency NIR source is very important. Fe 3+ as a promising NIR activator ion have ga...

Fused Triphenylamine‐Terminated Self‐Assembled Hole‐Transporting Monolayers for Perovskite Solar Cells

ABSTRACT Conventional self‐assembled hole‐transporting monolayers (SAMs) in perovskite solar cells (PSCs) suffer molecular aggregation, uneven coverage on rough FTO substrates, and insufficient interfacial defect passivation. The design and application of novel SAMs have become a...

Identifying ion and carrier behavior in perovskite solar cells through impedance spectra

Abstract Due to the interference of ion dynamics in perovskite materials, specifically the mixed ionic-electronic conduction property, the impedance response of perovskite solar cells exhibits numerous anomalous features. Herein, we conduct numerical simulations using the drift-d...

Optimization of Extraction Process for Total Flavonoids and Crude Polysaccharides from Nephrolepis cordifolia and Assessment of Their In Vitro Antioxidant Properties

This study systematically optimized the extraction processes of two bioactive constituents, total flavonoids and crude polysaccharides, from the dried underground tubers of Nephrolepis cordifolia (L.) C. Presl, and further comprehensively characterized their in vitro antioxidant...
