The demand for flexible and stretchable devices has been increasing in multiple fields, such as healthcare, energy harvesting, artificial intelligence. In this study, we report a novel method to fabricate by integrating kirigami sheet with an elastomer, both stretchable. Owing the flatness of under no stress, electrodes can be patterned using printing technique, which enable large size mass pro...

This paper presents a probabilistic-approach-based reliability prediction model of semiconductor light emitting devices. Using this model with given initial light-emitting performance and degradation behavior otherwise determined by experiment, the reliability function of the devices is obtained, and the results correlate well with experimental results. (Modeling the initial light-emitting perf...

[reaction: see text] Conjugated oligomers with an alternating phenylene-pyrimidine structure have been synthesized by the successive Suzuki coupling reaction starting from 2-bromo-5-iodopyrimidine. The photoluminescence properties and quasi-reversible redox behavior of these oligomers make them applicable as an active material for a light-emitting device. Blue light-emitting electroluminescent ...

This article introduces a previous study and tremendous progress in basic theoretical modeling, material developments and device engineering for polymer light-emitting devices (PLEDs).

We present a novel approach to enhance light emission in Si and demonstrate a sub-bandgap light emitting diode based on the introduction of point defects that enhance the radiative recombination rate. Ion implantation, pulsed laser melting and rapid thermal annealing were used to create a diode containing a self-interstitial-rich optically active region from which the zero-phonon emission line ...

Unlike a conventional white light source that emits a continuous and broad spectrum of light, the dual wavelength white light emitting diode (LED) generates white light by mixing blue and yellow lights, so there are two distinct peaks in its intensity spectrum. Prior works had shown that the spectral property of the dual wavelength white LED can affect the vertical scanning interferometry negat...

We apply a rigorous dipole model to analyze the light outcoupling and angular performance of quantum dot light emitting diode (QLED). To illustrate the design principles, we use a red QLED as an example and compare its performance with an organic light emitting diode (OLED). By combining a high refractive index glass substrate with macroextractors, our simulation results indicate that the light...
