Dispersive photoluminescence decay by geminate recombination in amorphous semiconductors

, 2005
The photoluminescence decay in amorphous semiconductors is described by power law $t^{-delta}$ at long times. The power-law decay of photoluminescence at long times is commonly observed but recent experiments have revealed that the exponent, $delta sim 1.

Luminescence in sulfides : a rich history and a bright future [PDF]

, 2010
Sulfide-based luminescent materials have attracted a lot of attention for a wide range of photo-, cathodo- and electroluminescent applications. Upon doping with Ce3+ and Eu2+, the luminescence can be varied over the entire visible region by appropriately

Excitation Enhancement of a Quantum Dot Coupled to a Plasmonic Antenna

, 2012
Plasmonic antennas are key elements to control the luminescence of quantum emitters. However, the antenna's influence is often hidden by quenching losses. Here, the luminescence of a quantum dot coupled to a gold dimer antenna is investigated.

Photoluminescent Ferroelastic Molecular Crystals [PDF]

Angewandte Chemie, 2020
AbstractFerroelasticity has been reported for several types of molecular crystals, which show mechanical‐stress‐induced shape change under twinning and/or spontaneous formation of strain. Aiming to create materials that exhibit both ferroelasticity and light‐emission characteristics, we discovered the first examples of ferroelastic luminescent ...

Dispersive diffusion controlled distance dependent recombination in amorphous semiconductors

, 2005
The photoluminescence in amorphous semiconductors decays according to power law $t^{-delta}$ at long times. The photoluminescence is controlled by dispersive transport of electrons.

Novel Tailoring of Ternary ZnS‐MXene‐TiO2 Nanocomposite Heterojunction and Its Tunable Electrochemical Properties With Enhanced Photocatalytic Degradation

Advanced Engineering Materials, EarlyView.
ZnS‐MXene‐TiO2 nanocomposite heterojunction for photocatalytic decomposition of this methylene blue dye (MB) greatly improves light absorption, charge separation, and active site area. Two‐dimensional MXene forms nanocomposites by easily combining them with 0D (quantum dots), 1D (tube and wire), 2D (plane and sheet), and 3D (particle and lamellar ...
