Quantifying Spin Defect Density in hBN via Raman and Photoluminescence Analysis

Advanced Functional Materials, EarlyView.
An all‐optical method is presented for quantifying the density of boron vacancy spin defects in hexagonal boron nitride (hBN). By correlating Raman and photoluminescence signals with irradiation fluence, defect‐induced Raman modes are identified and established an relationship linking optical signatures to absolute defect densities. This enables direct

Wafer‐Scale Synthesis of Mithrene and its Application in UV Photodetectors

Advanced Functional Materials, EarlyView.
A controlled tarnishing step on the silver surface precedes the solid‐vapor‐phase chemical transformation into silver phenylselenolate thin films. The approach yields crystals exceeding 1 µm with improved in‐plane orientation. Integration on graphene phototransistors demonstrates high photoresponsivity, positioning mithrene as a promising material for ...

High‐Rate FA‐Based Co‐Evaporated Perovskites: Understanding Rate Limitations and Practical Considerations to Overcome Their Impact

Advanced Functional Materials, EarlyView.
Vacuum‐based deposition is promising for perovskite solar cells to be successfully commercialized. However, co‐evaporation, the most common vapor phase deposition technique, suffers from very low deposition rates. In this work, we reveal that high deposition rates can lead to carbon flakes depositing into the perovskite absorber layers due to material ...

Unveiling Aggregation‐Induced Singlet Fission in Push–Pull Diketopyrrolopyrrole Water Dispersed Nanoaggregates and Thin Films

Advanced Functional Materials, EarlyView.
Aggregates of diketopyrrolopyrrole dipolar and quadrupolar systems exhibit panchromatic absorption spectra extending in the entire visible range. Upon aggregation in water and in the solid state, their fluorescence is almost completely quenched and their singlet excited state lifetime is significantly shortened.

Electrochemical Formation of BiVO4/BiPO4 Photoanodes for Enhanced Selectivity toward H2O2 Generation

Advanced Functional Materials, EarlyView.
In acidic KPi, V dissolves from the BiVO4 lattice, while adsorbed phosphate reacts with the electrode under an external bias, forming a BiPO4 surface layer. This BiPO4 layer exhibits stronger bicarbonate adsorption, redirecting the water oxidation pathway toward two‐electron H2O2 production.
