Fluorescence Tuning of Carbon Dots from Red to Blue via UV‐Induced Photochemical Etching

open access: yesAdvanced Science, EarlyView.
A UV‐driven photochemical process enables continuous color evolution of carbon dots from red to blue using a single irradiation parameter. Progressive photoetching restructures graphitic domains and surface states, allowing full visible‐spectrum emission control.

Integrated Optoelectronic Model to Predict the External Quantum Efficiency of Single‐Layer TADF Organic Light‐Emitting Diodes

open access: yesAdvanced Electronic Materials, EarlyView.
An experimentally validated optoelectronic device model is presented to describe the efficiency and roll‐off behavior of single‐layer TADF OLEDs. By coupling charge transport, exciton dynamics, and optical outcoupling, the model reproduces the External Quantum Efficiency (EQE) across different emission layer thicknesses and temperatures, offering ...

Iridium complex, a phosphorescent light-emitting diode material, serves as a novel chemical probe for imaging hypoxic tumor tissues [PDF]

open access: yes, 2007
Iridium complex, a promising organic light-emitting diode for next generation television displays, emits phosphorescence. Phosphorescence is quenched by oxygen. We used this oxygen-quenching feature for imaging tumor hypoxia.
