Journal Article
Patel, R., Trichet, A., Coles, D., Dolan, P., Fairclough, S., Leontiadou, M., …Smith, J. (2015). Gain spectroscopy of solution-based semiconductor nanocrystals in tunable optical microcavities. Advanced optical materials, 4(2), 285-290. https://doi.org/10.1002/adom.201500363

The lasing behavior of solution‐based colloidal quantum dots within an open microcavity is reported. The small size and wide tunability of the cavity provide single mode lasing over a wavelength range in excess of 25 nm. By extracting the lasing thre...

Ultrafast charge dynamics in trap-free and surface-trapping colloidal quantum dots (2015)
Journal Article
Smith, C., Leontiadou, M., Page, R., O'Brien, P., & Binks, D. (2015). Ultrafast charge dynamics in trap-free and surface-trapping colloidal quantum dots. Advanced Science, 2(10), 1500088. https://doi.org/10.1002/advs.201600165

Ultrafast transient absorption spectroscopy is used to study subnanosecond charge dynamics in CdTe colloidal quantum dots. After treatment with chloride ions, these can become free of surface traps that produce nonradiative recombination. A compariso...

Effect of chloride passivation on recombination dynamics in CdTe colloidal quantum dots (2015)
Journal Article
Espinobarro-Velazquez, D., Leontiadou, M., Page, R., Califano, M., O'Brien, P., & Binks, D. (2015). Effect of chloride passivation on recombination dynamics in CdTe colloidal quantum dots. ChemPhysChem, 16(6), 1239-1244. https://doi.org/10.1002/cphc.201402753

Colloidal quantum dots (CQDs) can be used in conjunction with organic charge‐transporting layers to produce light‐emitting diodes, solar cells and other devices. The efficacy of CQDs in these applications is reduced by the non‐radiative recombination... Read More about Effect of chloride passivation on recombination dynamics in CdTe colloidal quantum dots.
