A teaching tape for LQ-07, Fluorescence Energy Budget and Stokes's Rule

Journey I Stage G: The Fluorescence Energy Accounting

Interactive journey stage examining Stokes's rule, deviation cases, and weak-illumination proportionality.

Where it starts

The settings the tape begins from, under the constant set modern-si-2019. Values are the model's own, not the laboratory control's display: a radius of 5e-7 is half a micrometre.
SettingValue
Exciting Frequency ν₁ (nu1)850
Emitted Frequency ν₂ (nu2)850
Absorbed Quanta k (multiQuantumK)1
Absorbed Optical Power (absorbedPowerMicrowatts)1
Quantum Yield Y (quantumYield)0.5

What it changes, and what to expect

  1. Set Emitted Frequency ν₂ (nu2) to 900 changes what the run starts from

    The Single-Quantum Ledger

    Single-quantum energy accounting: h*nu1 = h*nu2 + E_other.

These are the values the tape's author recorded, not a result this page computed. Nothing here runs the instrument. Open LQ-07 with these settings: the link opens it with them already in place. Compare what it gives you with what is recorded here. The settings travel in the link and the laboratory reads them as it loads, so without JavaScript it opens at its worked example instead.
