Plasmonic nanoparticles present unique optical properties that render them extremely useful for application in many different fields. Current applications of plasmonic nanoparticles include their use as nanoheaters to effectively kill cancer cells, but they also contribute to the progress of solar energy technology. In this progress report, modern applications of plasmonic nanoparticles from which society may ultimately benefit are highlighted.
- Exciton–Polaron-Induced Aggregation of Organic Electroluminescent Materials: A Major Degradation Mechanism in Wide-Bandgap Phosphorescent and Fluorescent Organic Light-Emitting Devices

Phosphorescent and fluorescent materials as emitter guests aggregate as a result of electrical stress. Such electrical-driving-induced aggregation occurs more significantly in guest materials with wider bandgaps and less spatially symmetric structures. This process is mainly induced by interactions between excitons and positive polarons that reside on the guests.

A fully conjugated polycyanine (AJMPC02) showing a very large Re(γ) value of −9.0 × 10−57 mks at 1.3 μm is synthesized. It is used as a host polymer for anionic TCF-cyanines for creating a complementary polymeric cyanine salt complex, which exhibits a Re(γ) value of −5.6 × 10−57 mks at 1.3 μm. A good optical quality thin film based on AJMPC02-TCF gives a Re(γ) value of −2.1 × 10−18 mks at 1.3 μm and −8.5 × 10−19 mks at 1.55 μm, which are among the highest values reported for molecular materials, and much higher than those derived from silicon.
- Tuning a Weak Emissive Blue Host to Highly Efficient Green Dopant by a CN in Tetracarbazolepyridines for Solution-Processed Thermally Activated Delayed Fluorescence Devices

Cyanopyridine is used as a new electron-withdrawing unit for thermally activated delayed fluorescence (TADF). Solution-processed simple structure devices using 2,3,5,6-tetracarbazole-4-cyano-pyridine as a green TADF dopant show maximum external quantum efficiencies as high as 10.4% and 11.4% for devices with 2,3,5,6-tetracarbazole-pyridine and 1,3-bis(N-carbazolyl)benzene as host materials, respectively.
- Color-Tunable Photoluminescence and NIR Electroluminescence in Carbon Nitride Thin Films and Light-Emitting Diodes

Article first published online: 26 FEB 2015 | DOI: 10.1002/adom.201500019
Color-tunable photoluminescence from continuous graphitic carbon nitride (g-C3N4) thin films is demonstrated. The films are employed in light-emitting diodes. A strong redshift of the electroluminescence with respect to photoluminescence is observed and a model for this uncommon behavior is provided.
