Exciton–LO‐phonon interactions in a spherical quantum dot (QD) are studied theoretically in the weak confinement regime. The e–h exchange interaction makes it possible to lift the degeneracy of the lowest exciton levels via exciton–phonon interaction as the Jahn‐Teller effect. The Huang‐Rhys factor on the levels having maximum oscillator strength changes much slower than a —5 which is the radius a dependence in a large‐size limit studied in a previous work.
