Ultrafast Quenching of Excitons in the Zn<sub>x</sub>Cd<sub>1−x</sub>S/ZnS Quantum Dots Doped with Mn<sup>2+</sup> through Charge Transfer Intermediates Results in Manganese Luminescence

Ultrafast Quenching of Excitons in the Zn<sub>x</sub>Cd<sub>1−x</sub>S/ZnS Quantum Dots Doped with Mn<sup>2+</sup> through Charge Transfer Intermediates Results in Manganese Luminescence

For the first time, a specific time-delayed peak was registered in the femtosecond transient absorption (TA) spectra of Zn<sub>x</sub>Cd<sub>1−x</sub>S/ZnS (x~0.5) alloy quantum dots (QDs) doped with Mn<sup>2+</sup>, which was interpreted as the electrochromic Sta...
