    Center for Basic Sciences, National Renewable Energy Laborarory, Golden, Colorado 80401, USA
    Nano Lett 5:865-71. 2005
    ..We present experimental and theoretical values of the size-dependent interband transition energies for PbSe QDs, and we also introduce a new model for MEG based on the coherent superposition of multiple excitonic states...
