Chemical Pressure‐Induced FWHM Narrowing in Narrowband Green Phosphors for Laser Displays with Ultra‐High Saturation Thresholds

Advanced Science, EarlyView.
Spectral tailoring is achieved in the phosphor Na0.6Rb0.4BaB9O15 (NRBBO): Eu2+ using chemical pressure. The gradual decrease of FWHM under chemical pressure of Rb+ ions. WLED based on NRBBO: 0.11Eu2+ have a color gamut of 106% NTSC. The excellent laser excitation properties of NRBBO: 0.11Eu2+ give it great potential as a green phosphor for laser ...

Low‐κ Extension Doping for High‐Performance Carbon Nanotube Transistors: Toward High‐Speed, Energy‐Efficient Electronics

Advanced Science, EarlyView.
This study presents the first experimental demonstration of a low‐κ extension doping strategy for CNT MOSFETs using stacked SiOx/AlFx layers. The proposed approach minimizes parasitic capacitance and reduces total resistance by 85%, significantly enhancing device performance. These findings establish a scalable, ultra‐thin doping method for high‐speed,

Photovoltaic and Photomultiplication Dual‐Mode Near‐Infrared Organic Detectors with Large Dynamic Range for Intensive and Faint Light Sensing

Advanced Science, EarlyView.
A photovoltaic/photomultiplication dual‐mode organic photodetector is developed by integrating two different organic bulk‐heterojunctions, one introduces the photovoltaic effect, and the other triggers photomultiplication charge generation in the stacked device at different voltage polarities.
