Controllable Preparation of Millimeter‐Scale In‐Plane Charged Domain Wall in a Lead‐Free Ferroelectric Film

Advanced Science, EarlyView.
This study presents an effective method for fabricating millimeter‐scale continuous in‐plane head‐to‐head charged domain walls by controlling the growth of the Na0.5Bi0.5TiO3 film. The formation of antiphase boundaries plays a crucial role in stabilizing the charged domain walls. Atomic‐scale insights reveal that the dynamic coupling among polarization,

Determination of the Kinetic Rates and Intrinsic Nonradiative Losses in Organic Thermally Activated Delayed Fluorescence Emitters

Advanced Science, EarlyView.
It is demonstrated that the kinetic rates and intrinsic nonradiative losses of purely organic emitters with thermally activated delayed fluorescence cannot be precisely determined by photoluminescent measurements alone. With device modeling, it is then possible to quantify the absolute nonradiative losses from singlets and triplets, and therefore the ...
