:<math>E_{b} = 2 E_{X} - E_{XX}</math>
where <math>E_{XX}</math> is the biexciton energy, <math>E_{X}</math> is the exciton energy, and <math>E_{b}</math> is the biexciton binding energy.
:<math>E_{b}</math> is the biexciton binding energy.
When a biexciton is annihilated, it disintegrates into a free exciton and a photon. The energy of the photon is smaller than that of the biexciton by the biexciton binding energy,
