Abstract
PurposeThe paper aims to provide a technical review of the application of quantum dot (QD) technology to sensors.Design/methodology/approachFollowing a brief introduction to QD technology, this paper considers recent research on QD‐based physical, chemical and gas sensors.FindingsThis shows that QDs are being exploited in a range of experimental sensors for detecting physical variables, notably radiant/electromagnetic quantities and temperature; chemical compounds, such as metals and many species of clinical interest; and a variety of gases and vapours. Prospects also exist to develop improved sources and detectors for use in optical gas sensors.Research limitations/implicationsThe paper does not consider biomedical uses of QDs such as cellular imaging, bioassays and biosensors.Originality/valueThis provides a detailed insight into recent research on physical, chemical and gas sensors based on QD technology.
