- Hence, excitons bound to impurities and defects possess giant oscillator strength.
- Where f _ { nk } are oscillator strengths for quantum transitions between the states n and k.
- The only drawback of f-f transitions are their faint oscillator strengths which may in fact be turned into an advantage.
- Shallow impurity-exciton states are working as antennas borrowing their giant oscillator strength from vast areas of the crystal around them.
- High oscillator strength results in low-power optical saturation and radiative life times \ tau _ i \ approx 500 ps.
- Giant oscillator strengths of impurity excitons endow them with ultra-short radiational life-times \ tau _ i \ sim1 ns.
- In CdS, with E _ i \ approx6 meV, were observed impurity-exciton oscillator strengths f _ i \ approx 10.
- The first largely complete set of oscillator strengths of singly ionized iron-group elements were made available in the 1960s, and these were subsequently improved.

- Impurities can bind excitons, and when the bound state is shallow, the oscillator strength for producing bound excitons is so high that impurity absorption can compete with intrinsic exciton absorption even at rather low impurity concentrations.
