Cu–Fe–S-Based Colloidal Quantum Dots with Strong and Reversible Luminescence Photobleaching for Optical Data Storage

Cu–Fe–S-Based Colloidal Quantum Dots with Strong and Reversible Luminescence Photobleaching for Optical Data Storage

CuFeS<sub><i>x</i></sub> (CFS) core–shell quantum dots (QDs) synthesized via a high-temperature colloidal chemistry route demonstrate unusually strong photobleaching of their luminescence under irradiation with blue light. Cw laser irradiation at λ = 440 nm results in a subst...
