Quantum dots (QDs) thin film sensor was developed to detect fungicide in water by optical sensing system. The ZnCdSe QDs was synthesized using a wet-chemical process to apply in this fluorescent sensor. A sensor system was setup, comprises an excitation light source made of laser diode, a dual arm fiber optic probe, a spectrometer and sensor chamber. The QDs thin film was deposited by dropping QDs...
This paper reports the fabrication of a quantum dots (QD)-organics hybrids light-emitting diode (LED) for potential light sources. Organic light emitting diode (OLED) have become a focus of attention since past decades for potential light sources in a flat panel displays applications. Despite their intriguing performance in producing rich-color light emission, they still faced several critical defects,...
Quantum dots (QDs) have been attracted an active interest for light emitting device due to their unique high luminescence efficiency and narrow emission spectra as a result of the strong electrons confinement in its nanoscale core that is potential for production of pure colour light emission. In this work, a CdSe quantum dot-PHF organic hybrid light emitting devices have been fabricated. To study...
This paper reports the synthesis of highly lumimescence CdSe quantum dots via wet-chemical process and the study of the surfactant concentration effect on the improvement of the photoluminescence characteristic. Here, we also discussed in detail the quantum dots synthesis procedure and the mechanism for the improvement of the luminescence characteristic of CdSe quantum dots under a different surfactant...
