Interdigitated Array

We demonstrated electroluminescence from hybrid 1D glass fibres incorporating CdTe quantum dots with a thin SiO2 overlayer which contains CdS-like clusters. The self-organised fibres, prepared by refluxing precursor nanowires, exhibited red electroluminescence on Au interdigitated array electrodes at room temperature. Although fluctuation with time was observed in the electroluminescence, relatively low threshold electric field (2.6 × 106 V m–1) suggests that the CdTe quantum dots-based hybrid fibres are expected to be applied to low voltage driven electroluminescent devices.

Benefiting from the low (2-fold) degeneracy of the lowest quantized states of orthorhombic Ag2Se quantum dots, room-temperature near-infrared lasing with a low threshold (163 μJ cm−2) is achieved.
