Quantum Dot Blinking Suppression (2D)

2D canvas quantum-dot blinking simulator: a single dot switches ON/OFF with real power-law-distributed dwell times (not exponential), with a live log-log dwell-time histogram and a shell-thickness slider that measurably raises the on-time fraction.

Colloidal quantum dots don't emit light steadily — a single dot randomly switches between a bright "ON" state and a dark "OFF" state, a phenomenon called fluorescence intermittency or blinking, and real dwell times in each state follow a power law, not a simple exponential. This 2D canvas simulator samples ON/OFF dwell times directly from a truncated power-law distribution via inverse-transform sampling, and ties the ON-state cutoff to the same Auger-ionization physics as the 3D version: grow a thicker CdS/ZnS shell, reduce surface trap density, or dial back the excitation rate, and watch the power-law's heavy tail stretch, the on-time fraction climb, and the log-log dwell-time histogram flatten — exactly the statistic real "giant-shell" non-blinking quantum dots exploit for single-molecule imaging.

⚙ Under the hood

Watch a single core/shell quantum dot switch between a bright ON exciton state and a dark, Auger-charged OFF state, then tune shell thickness, surface trap density and excitation rate to suppress fluorescence blinking.
