Quantum Dot Photoluminescence — 2D Jablonski & Decay-Curve Diagram

This 2D counterpart renders the exact same competing radiative/non-radiative photophysics as an energy-level diagram and a time-resolved decay curve rather than a spatial camera view. A Jablonski diagram places each quantum dot on a ground or excited energy band — a physically meaningful vertical axis, not an arbitrary 3D position — while every radiative decay drops a photon into a live TCSPC-style decay-curve panel whose histogram reconstructs the exponential survival curve N(t)=N₀·exp(−t/τ), the same way a real lab instrument measures quantum yield and lifetime.
