| dc.description.abstract | The coupling between exciton and longitudinal optical (LO) phonon was investigated in the use of temperature-dependent photoluminescence from Mg(x)Zn(1-x)O powders prepared by a sol-gel method in the range of 0 <= x <= 0.05. The exciton binding energy increases to 73 meV for 5 at. % Mg incorporated powders. The strength of exciton-LO phonon coupling was deduced from the energy shift of exciton emission with temperature variation. The increase of the exciton binding energy results from a decrease of the exciton Bohr radius that is responsible for reducing the coupling strength of exciton-LO phonon as increasing Mg content.
