ABSTRACT
We report on measurements of room-temperature electroluminescence from single silicon nanocrystals. The electrically driven emission reveals typical characteristics of single-nanocrystal luminescence: the peak wavelength variations, narrowing of spectral bands, a high degree of linear polarization, and intensity fluctuations (blinking) observed on a scale of minutes. From the count rate statistics of individual nanocrystals, we conclude that the yield of radiative emission is as high as 19%. These findings may open a route to highly efficient all-silicon light emitters. © 2004 American Institute of Physics.

    During porous etching of GaP, electroluminescence ranging from the ultraviolet to the near-infrared is generated at the interface of the porous and the nonporous layer. This is used to measure the wavelength-dependent transmission of light through porous layers in a wide thickness range. Two...

    IR irradiation of electroluminescent emitters based on thin ZnS:Mn films in the pause between excitation voltage pulses produces quenching of the luminescence and leads to a decrease in the emission intensity within the wavelength interval 530–540 nm and an increase within 640–680...
