Efficient sky-blue perovskite light-emitting diodes via photoluminescence enhancement

Nature Communications, 2019
The efficiencies of green and red perovskite light-emitting diodes (PeLEDs) have been increased close to their theoretical upper limit, while the efficiency of blue PeLEDs is lagging far behind.

Phonon-assisted up-conversion photoluminescence of quantum dots

Nature Communications, 2021
Phonon-assisted up-conversion photoluminescence can boost energy of an emission photon to be higher than that of the excitation photon by absorbing vibration energy (or phonons) of the emitter.

Confined-domain crosslink-enhanced emission effect in carbonized polymer dots

Light: Science & Applications, 2022
Confined-domain crosslink-enhanced emission effect was first studied to reveal the photoluminescence mechanism of carbonized polymer dots (CPDs). A general strategy was exploited to synthesize CPDs exhibiting tunable photoluminescence properties.

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

Advanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Enhancement of exciton photoluminescence intensity caused by the distortion of the crystal plane originating from the internal strain in a ZnO wafer

AIP Advances, 2011
We have investigated the relation between the exciton photoluminescence intensity and distortion of the crystal plane in a ZnO wafer. The present investigation utilizes the following two characterization methods that complement the result of the ...
