1. A thermophotovoltaic electric power generating system comprising:

  • a ceramic emitter comprising a metal oxide having a low emissivity in about the same range as the emissivity of aluminum oxide, gallium oxide, thorium oxide, yttrium oxide, zirconium oxide, and at least one thermally stimulated quantum emitter material for emitting radiation in at least two wavelength bands when heated above a threshold temperature; and

    a multilayer photovoltaic collector matched to the emitter for selectively absorbing radiation in the same wavelength bands emitted by the emitter.
