From: Highly Responsive Ultraviolet Sensor Based on ZnS Quantum Dot Solid with Enhanced Photocurrent
Photocurrent properties for ZnS QD solid prepared at (a) 24 hrs, (b) 48 hrs, samples recorded at different biasing voltage (0.5 and 1.0)Volt and (c) Schematic representation of electron transfer process between the cluster like QD solid and TiO2 film reducing the electron recombination with increasing electron transfer rate.
