With the breakthrough of mobility in quantum dot electric field transistors (Q-EFTs), the potential application in these functional devices has revealed and been paid more attentions, due to flexibility in design, low cost, facility for processing and large area. One of the most important applications of FETs is the photoconductive detector. However, these functional FETs have less been reported. In this work, colloidal PbS Q-FETs were successfully fabricated by reasonable structure design and layer-by-layer depositon technique PbS quantum-dots. The bipolar property was demonstrated by the output and transfer characteristics, as devices work in I and III quadrants simultaneously. The mobilities of electron and hole are 0.16 cm2/(V⋅s) and 0.28 cm2/(V⋅s), respectively. Q-FETs work as photoconductive detectors at both positive and negative gate bias voltages. Under constant gate bias, photocurrent increase exponentially with the intensity of light. The responding region consisted with the absorption range of PbS quantum dots. A linearity was found in drain voltage and incidence of laser power, the ratio was attributing to 0.0019 (μW⋅V)-1.

Time Of Reaction

Herein, we report the synthesis of PbS Quantum Dots (QDs) with oleic acid as surfactant molecules by non coordinating solvent route. The particles are having better size tunability by varying temperature and time of reaction. These quantum dots are characterized by optical absorption, photoluminescence and transmission electron microscopy. The resulting colloids are highly stable, extremely small size, spherical in shape, monodisperse and strong band emission. The estimated particles sizes are in the range of 2 to 6 nm. The present method of synthesis of PbS quantum dots can be used to fabricate low cost electronic devices.
