Tripling the Optical Efficiency of Color-Converted Micro-LED Displays with Funnel-Tube Array

Crystals, 2019
Color-converted micro-LED displays consist of a mono-color micro-LED array and color conversion materials to achieve full color, while relieving the burden of epitaxial growth of three-color micro-LEDs. However, it usually suffers from low efficiency and

Investigation of high-performance perovskite nanocrystals for inkjet-printed color conversion layers with superior color purity

APL Photonics, 2021
We synthesized cesium lead-halide perovskite colloidal nanocrystals using the hot injection method for wide-color-gamut low-cost displays. An efficient surface defect passivation technique was applied to further improve the optical performance of the ...

Time-dependent photoionization of azulene: Competition between ionization and relaxation in highly excited states [PDF]

, 2008
Pump-probe photoionization has been used to map the relaxation processes taking place from highly vibrationally excited levels of the S2 state of azulene, populated directly or via internal conversion from the S4 state.

Improvement of conversion efficiency of atom-molecule Bose-Einstein condensate

, 2007
We investigate the stimulated Raman adiabatic passage in two-color photoassociation for a atom-molecule Bose-Einstein condensate. By applying two time-varying Guassian laser pulses that fulfill generalized two-photon resonance condition, we obtain highly
