Recent Advances in Luminescence-Based Sensors

Dear Colleagues,

Luminescence-based sensors constitute a specific type of optochemical sensor and can offer advantages of high sensitivity, high selectivity, and non-invasive measurements. They can also render reversibility, ease of miniaturization, and low costs. In recent years, tremendous effort has been devoted to the development of luminescence-based sensors. These luminescence-based sensors include fluorescence turn-on/turn-off sensors and ratiometric fluorescence sensors, and have been used in various sensing applications such as the detection of explosive chemicals, metal ions, anions, small organic molecules, biochemical molecules, pH, temperature, and others.

To date, many luminescent sensory materials have been developed for luminescence-based sensors. Among them, metal-organic frameworks (MOFs) have been extensively explored due to their unique crystallinity, tuneable porosity, structural diversity, abundant functional groups, and excellent chemical stability. Their luminescence can be generated from organic linkers and metal ions, as well as the interactions among them. In addition, the luminescence feature can also be adjusted by post-functionalization or encapsulation of luminescent guest species. In addition, carbon dots (CDs), covalent organic frameworks (COFs), layered double hydroxides (LDHs), and nanoclusters for coinage metals (Cu, Ag, and Au) are also emerging as paradigms to design luminescent materials for luminescence-based sensors.

The aim of this Special Issue is to collect papers on the recent advances in luminescence-based sensors from researchers and experts. The contributions can be studies on rational design/construction principles, synthesis strategies, mechanisms, and diverse applications of luminescent materials for luminescence-based sensors. I would like to cordially invite you to submit an article to this Special Issue. Full papers, short communications, and reviews are all welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
