Quantum Dot Blinking — Fluorescence Intermittency

Interactive 3D simulation of single quantum-dot photoluminescence blinking: watch a nanocrystal flicker between bright and dark states with power-law-distributed on/off durations, the same statistics measured in real single quantum-dot spectroscopy.

Quantum Physics3DModerate60 FPS📱 Mobile-adapted⇄ 2D version

Single colloidal quantum dots don't fluoresce steadily under continuous illumination — they randomly flicker between a bright, photon-emitting state and a dark state where an ejected charge carrier quenches emission via Auger recombination. This simulation renders that blinking nanocrystal in 3D, sampling ON- and OFF-state durations from a truncated power-law distribution — the same statistical signature (no characteristic timescale, occasional very long dark excursions) measured in real single quantum-dot spectroscopy experiments. Tune the ON/OFF power-law exponents and the long-time cutoff, and watch the live intensity trace and running statistics build up in real time.

⚙ Under the hood

Watch a single quantum dot randomly switch between bright and dark fluorescence states, with ON/OFF durations drawn from a truncated power-law distribution matching real single quantum-dot blinking statistics.
