Synthesis of Core–Shell Te@Se Quantum Dots and Their Broadband Photodetector Performance in Low Concentration Electrolytes

open access: yesLaser &Photonics Reviews, EarlyView.
Te@Se core–shell heterojunction quantum dots (QDs) are synthesized by a two‐step strategy via combining liquid‐phase exfoliation and epitaxial growth. As active materials in photoelectrochemical photodetectors, Te@Se QDs exhibit excellent photo‐response performance in low‐concentration electrolytes and deionized water.

Minimizing Defects in Blue‐Emitting ZnSeTe Quantum Dots Using ZnF2 Throughout Core and Shell Growth

open access: yesSmall, EarlyView.
Near‐unity photoluminescence quantum yield (PLQY = 0.98) in blue ZnSeTe quantum dots is achieved by integrating ZnF2 throughout all growth stages. ZnF2 performs two key functions: generating HF in situ for structural defect removal and simultaneously promoting X‐ and Z‐type ligand attachment for effective surface passivation.

Electrically Tunable Tunneling and Spectral Response in WSe2/h‐BN/CdSe/Graphene Heterostructure

open access: yesSmall, EarlyView.
In the WSe2/h‐BN/CdSe quantum dot/graphene heterostructure, the graphene voltage dynamically tunes the tunneling barrier and energy alignment across the h‐BN layer. The bias‐dependent Fermi‐level alignment enhances the tunneling density of states, leading to efficient extraction of photo‐excited electrons from QDs into WSe2 and graphene.
