ControlsMaterial buttons (CdSe / CdS / PbS / InP) switch the bulk bandgap and electron/hole effective masses; dot size slider (L, 1-10 nm) sets the confinement length and redraws the electron and hole energy ladders and the E_gap(L) curve; transition n slider (1-4) selects which confined electron/hole rung pair recombines, shifting the emitted photon's wavelength and the live color swatch.
