Ultrafast photoinduced enhancement of nonlinear optical response in 15-atom gold clusters on indium tin oxide conducting film

, 2013
We show that the third order optical nonlinearity of 15-atom gold clusters is significantly enhanced when in contact with indium tin oxide (ITO) conducting film.

Optical polarization of nuclear ensembles in diamond

, 2013
We report polarization of a dense nuclear-spin ensemble in diamond and its dependence on magnetic field and temperature. The polarization method is based on the transfer of electron spin polarization of negatively charged nitrogen vacancy color centers ...

Highly sensitive switching of solid-state luminescence by controlling intersystem crossing

Nature Communications, 2018
The development of intelligent materials, in particular those showing the highly sensitive mechanoresponsive luminescence (MRL), remains challenging. Here the authors report a strategy for constructing high performance On-Off MRL materials by introducing

Bodipy Derivatives as Triplet Photosensitizers and the Related Intersystem Crossing Mechanisms

Frontiers in Chemistry, 2019
Recently varieties of Bodipy derivatives showing intersystem crossing (ISC) have been reported as triplet photosensitizers, and the application of these compounds in photocatalysis, photodynamic therapy (PDT), and photon upconversion are promising.

Immense magnetic response of exciplex light emission due to correlated spin-charge dynamics

, 2016
As carriers slowly move through a disordered energy landscape in organic semiconductors, tiny spatial variations in spin dynamics relieve spin blocking at transport bottlenecks or in the electron-hole recombination process that produces light. Large room-

Dissipation and dynamics in ultrafast intersystem crossings

The Journal of Chemical Physics, 2020
The effects of dynamics and dissipation on ultrafast intersystem crossings are studied for a dissipative two-level system coupled to a local vibronic mode. A method of amplitude damping of the wave packet is presented that accounts better for the position of the wave packet and avoids spurious transitions between potential wells.

Facile Synthetic Access Towards Sulfur- and Selenium-Functionalized Boron-Based Multiresonance TADF Emitters

Molecules
Thermally activated delayed fluorescence (TADF) materials with high photoluminescence quantum yields and a fast reverse intersystem crossing (RISC) are of the highest interest for organic light-emitting diodes (OLEDs). In the past decade, triaryl boranes

Reverse intersystem crossing mechanisms in doped triangulenes

Physical Chemistry Chemical Physics
Electronic structure calculations suggest that reverse intersystem crossing in B and N-doped triangulenes can occur via both direct (spin–orbit coupling) and mediated (spin–vibronic coupling) mechanisms.
