Notes:
The development of a completely new class of artificially engineered phosphors for electroluminescent displays is proposed in which deep quantum wells embedded in a high band gap material act as radiative centers. The proof of concept of such phosphor activation by quantum wells (QWs) has been demonstrated in the CdSe/SrS multi-quantum well system prepared by atomic layer epitaxy. Various QW widths (3–15 nm) were studied. The reduction in QW width shifts the emission towards shorter wavelength and the emission spectra exhibit multiple peaks, believed to be the result of transitions from several QW levels. © 1997 American Institute of Physics.
