Suppressed Stokes Shifts and Hot Luminescence from Quantum Dots within Plasmonic Nanocavities

open access: yesAdvanced Optical Materials, EarlyView.
This study demonstrates the suppression of the Stokes shift in lead sulfide quantum dots through integration with plasmonic nanocavities. By enhancing spontaneous emission and altering exciton relaxation pathways, this approach enables direct band‐edge emission with improved radiative efficiency, highlighting the powerful role of nanophotonic ...

Optical Properties of Thin Films of Tin Iodide Perovskite Nanostructures

open access: yesAdvanced Optical Materials, EarlyView.
A comprehensive spectroscopic study of thin films of 3D CsSnI3 nanocrystals (NCs) that coexist with residual 2D Ruddlesden‐Popper nanosheets (NSs) has been performed. Polymer encapsulation enables solid‐state stabilization of the tin iodide perovskite nanostructures, while insight into the energetics and dynamics of the NC and NS excitons is provided ...

Toward Sustainable Photocatalysis: Addressing Deactivation and Environmental Impact of Anodized and Sol–Gel Photocatalysts

open access: yesAdvanced Sustainable Systems, EarlyView.
A life‐cycle evaluation of TiO2 photocatalysts for water purification compares the effectiveness of Sol–Gel vs anodic oxides in tetracycline mineralization, targeting deactivation, regeneration, and environmental impact from a cradle‐to‐grave perspective.

Dual Charge Transfer Mechanisms in Intimately Bonded S‐scheme Heterojunction Photocatalyst with Expeditious Activity toward Environmental Remediation

open access: yesAdvanced Sustainable Systems, EarlyView.
A novel MBOdCN S‐scheme heterojunction photocatalyst is fabricated using pristine Mg‐Bi2O3 and grayish g‐C3N4, where dynamic dual charge migration paths occur to accelerate exciton dissociation. This composite catalyst realizes high degradation efficiency of up to 99.56% of oxytetracycline (OTC) removal under optimized conditions. The material exhibits
