Singlet-Triplet Splittings in the Luminescent Excited States of Colloidal Cu(+):CdSe, Cu(+):InP, and CuInS2 Nanocrystals: Charge-Transfer Configurations and Self-Trapped Excitons.

Journal of the American Chemical Society

Knowles KE, Nelson HD, Kilburn TB, Gamelin DR.
PMID: 26389577
J Am Chem Soc. 2015 Oct 14;137(40):13138-47. doi: 10.1021/jacs.5b08547. Epub 2015 Oct 05.

The electronic and magnetic properties of the luminescent excited states of colloidal Cu(+):CdSe, Cu(+):InP, and CuInS2 nanocrystals were investigated using variable-temperature photoluminescence (PL) and magnetic circularly polarized luminescence (MCPL) spectroscopies. The nanocrystal electronic structures were also investigated by absorption...

J Phys Chem Lett. 2015 Aug 06;6(15):3076-81. doi: 10.1021/acs.jpclett.5b01137. Epub 2015 Jul 23.

Impurity ions can transform the electronic, magnetic, or optical properties of colloidal quantum dots. Magnetic impurities introduce strong dopant-carrier exchange coupling that generates giant Zeeman splittings (ΔEZ) of excitonic excited states. To date, ΔEZ in colloidal doped quantum dots...

Photobiomodulation and the brain: a new paradigm.

Journal of optics (2010)

Hennessy M, Hamblin MR.

J Opt. 2017 Jan;19(1):013003. doi: 10.1088/2040-8986/19/1/013003. Epub 2016 Dec 14.

Transcranial photobiomodulation (PBM) also known as low level laser therapy (tLLLT) relies on the use of red/NIR light to stimulate, preserve and regenerate cells and tissues. The mechanism of action involves photon absorption in the mitochondria (cytochrome c oxidase),...

Mechanisms in photodynamic therapy: part one-photosensitizers, photochemistry and cellular localization.

Photodiagnosis Photodyn Ther. 2004 Dec;1(4):279-93. doi: 10.1016/S1572-1000(05)00007-4.

The use of non-toxic dyes or photosensitizers (PS) in combination with harmless visible light that is known as photodynamic therapy (PDT) has been known for over a hundred years, but is only now becoming widely used. Originally developed as...

Size dependence of negative trion Auger recombination in photodoped CdSe nanocrystals.

Nano letters

Cohn AW, Rinehart JD, Schimpf AM, Weaver AL, Gamelin DR.

Nano Lett. 2014 Jan 08;14(1):353-8. doi: 10.1021/nl4041675. Epub 2013 Dec 17.

We report a systematic investigation of the size dependence of negative trion (T(-)) Auger recombination rates in free-standing colloidal CdSe nanocrystals. Colloidal n-type CdSe nanocrystals of various radii have been prepared photochemically, and their trion decay dynamics have been...

Surface-Initiated Polymerization with Poly(.

Macromol Res. 2017 Feb;25(2):97-107. doi: 10.1007/s13233-017-5009-9. Epub 2017 Jan 12.

New methods are needed for covalent functionalization of nanoparticles-surface with organic polymer coronas to generate polymeric nanocomposite in a controlled manner. Here we report the use of a surface-initiated polymerization approach, mediated by titanium (IV) catalysis, to grow poly(
