Electroluminescence of Hybrid Self-Organised Fibres Incorporating CdTe Quantum Dots

Abstract

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.
