Directional Polarized Light Emission from Thin‐Film Light‐Emitting Diodes

Advanced Materials, 33(9), 2006801.

By: X. Fu, Y. Mehta n, Y. Chen*, L. Lei n, L. Zhu n , N. Barange n, Q. Dong n, S. Yin n  ...

author keywords: beam shaping; organic light-emitting diodes; perovskite light-emitting diodes; polarized light; waveguides
TL;DR: By selectively diffracting the transverse electric (TE) waveguide mode while suppressing other optical modes in a nanostructured LED, the authors demonstrate highly directional light emission from a full-area organic LED with a small divergence angle less than 3° and a TE to transverse magnetic (TM) polarization extinction ratio of 13.6%.

Efficient Energy Funneling in Quasi-2D Perovskites: From Light Emission to Lasing

ADVANCED MATERIALS, 32(16).

By: L. Lei n, D. Seyitliyev n, S. Stuard n, J. Mendes n, Q. Dong n, X. Fu, Y. Chen n, S. He  n ...

author keywords: amplified spontaneous emission; distributed-feedback lasers; energy funneling; light-emitting diodes; quasi-2D perovskites
TL;DR: The results show that it is important to control the morphology of the quasi-2D films to achieve efficient energy transfer, which is a critical requirement for light-emitting devices. (via Semantic Scholar)

Recovering cavity effects in corrugated organic light emitting diodes

OPTICS EXPRESS, 28(21), 32214–32225.

By: X. Fu, Y. Chen*, D. Shin n, Y. Mehta n, I. Chen*, N. Barange n, L. Zhu n , S. Amoah n, C. Chang*, F. So n 

TL;DR: It is found that the cavity effects can be partially recovered using a low index Teflon layer inserted between the ITO anode and the substrate due to the enhancement of the reflectance of the corrugated electrodes. (via Semantic Scholar)
