Sonochemical-assisted synthesis of CsPbBr3 perovskite quantum dots using vegetable oils†
Cesium lead halide (CsPbX3) perovskite quantum dots (PQDs) have attracted attention for use as absorber materials in photovoltaics as they show tuneable bandgap energy and high photoluminescence quantum yields together with the potential to demonstrate long-term stability and simple solution processability. Currently, the colloidal synthesis of PQDs relies to a large extent on the use of toxic and fossil derived solvents as the reaction medium. Alternative methods that partially or completely replace such solvents are anticipated as a step forward in meeting the sustainability criteria for the large-scale synthesis of PQDs. Herein, we report an eco-friendly sonochemical-assisted synthesis of CsPbBr3 PQDs using commercial vegetable oil solvents as the reaction medium. The effect of different vegetable oils on the synthesis and properties of PQDs was investigated in detail. The as-prepared CsPbBr3 colloids show similar photoluminescence (PL) spectra and crystalline structure to colloids obtained in mineral oil, which was used here for comparative purposes. Furthermore, a smaller amount of the optically inactive Cs4PbBr6 hexagonal crystalline phase was detected in the green synthesis compared to mineral oil-based synthesis. Finally, spin-coated thin films were produced, demonstrating the processability of the colloidal PQDs obtained via the green synthesis described here.
期刊介绍:
Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
