title: Imaging electroluminescence from individual nanoparticles in an array exhibiting room temperature single electron effect.
abstract: Electroluminescence (EL) from the monolayer of a network of a one-dimensional (1D) necklace of 10 nm Au particles (nano)cemented by CdS is imaged. The EL and photoluminescence (PL) spectra confirm the emission from CdS. The EL emission blinks and is highly specular. The position of the speckles from individual CdS cement sites is independent of magnitude and polarity of the applied bias. The EL is explained by field-assisted ionization of the cement due to high internal fields in the array caused by stationary local charging that also leads to robust single electron effect at room temperature.
