Tuning Optoelectronic Properties and Photoelectrochemical Performance of β‐TaON via Vanadium Doping

Small, EarlyView.
Vanadium‐doped β‐TaON is studied to elucidate how controlled cation substitution modulates crystal and electronic structures and photoelectrochemical performance. Moderate vanadium incorporation (<10 at.%) retains phase purity, narrows the bandgap, and improves charge transport, whereas excessive doping (>10 at.%) induces secondary phases that suppress
