Hybrid Colloidal Quantum Dot Nanocomposite Lasers for Flexible Photonics

Project: Research

Project Details


This project explored an innovative hybrid technology of mechanically-flexible lasers based on semiconductor colloidal quantum dots. The motivation was to enable visible lasers that are suitable for integration in wearable photonic systems and for applications in (bio)-sensing.

Key findings

1/ Record threshold performance of a colloidal quantum dot laser operating in the nanosecond regime
2/ Demonstration of the first proposal of a colloidal quantum dot laser sensor
3/ Mechanical wavelength tuning of the lasers
4/ Ultra-thin glass encapsulation embodiment that has since been extended to other solution-processed materials (e.g. organic semiconductor) and to non-laser application (e.g. colour-conversion of LEDs)
5/ An ultra-photostable, diode-pumped organic semiconductor laser
6/ Bio-molecular detection with an organic semiconductor laser
