Thermoelectric Gating Organic Electrochemical Transistors Enabled by Printable Ionogels With n‐p Convertible Thermopower

Advanced Science, EarlyView.
A type of thermoelectric ionogels with convertible n‐p thermopowers are demonstrated with Seebeck coefficients ranging from ‐3.61 to +9.74 mV K−1. Thus, thermoelectric gating organic electrochemical transistor is achieved by employing ionogel as thermoelectric modules and ionic dielectrics simultaneously, paving the road to self‐powered, highly ...

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

Advanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

Trap Depth Modulation and Antenna Effect of Organic Ligands for Enhancing Rare‐Earth Long Persistent Luminescence

Advanced Science, EarlyView.
Different from the current research trends that mainly focus on optimizing a single color system, a universal organic–inorganic hybrid strategy is proposed, aiming to synergistically enhance the luminescent properties of red, green, and blue multi‐color inorganic long‐persistent phosphorescent materials by trap depth modulation and antenna effect of ...
