Special Issue Information

Dear Colleagues,

As an important branch of photoelectric information technology, infrared photodetectors can realize imaging through successfully converting the incident infrared light into measurable electrical signals. Usually, the quality of infrared imaging is directly determined by the performance of the infrared photodetector. In recent years, with the wide application and increasing demand, the new generation of infrared photoelectricity technology with the characteristics of high sensitivity and being multi-band, lightweight and intelligent is constantly developing. Specially, with the discovery and reporting of novel materials and structures, infrared photodetectors show more research points in device structure, response mechanism and imaging system. Notably, infrared photodetectors are developing in the direction of high-performance, multi-spectrum, low-cost, large array and lightweight photodetectors, and have been widely used in military and civilian fields such as aerospace, precision guidance, medical epidemic prevention and intelligent driving, etc.

This Special Issue aims to publish selected contributions on recent advances in infrared photodetection and imaging, including original research articles and reviews. Potential topics include, but are not limited to:

infrared photodetection;
infrared imaging system and mechanism;
infrared photoelectricity technology;
novel infrared materials and system;
dual-/multi-color infrared photodetection;
future development of infrared photodetection;
application of infrared photodetection

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Photonics is an international peer-reviewed open access monthly 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 2400 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.

Monolayer black phosphorus (BP) holds great promise for naturally hyperbolic polaritons and correlated states in rectangular moiré superlattices. However, preparing and identifying high-quality monolayer BP are challenging due to its instability and high transparency, which limits extensive studies. In this study, we developed a method for rapidly and nondestructively identifying monolayer BP and its crystal orientation simultaneously using modified photoluminescence (PL) microscopy. The optical contrast of monolayer BP has been significantly increased by at least twenty times compared to previous reports, making it visible even on a transparent substrate. The polarization dependence of optical contrast also allows for the in situ determination of crystal orientation. Our study facilitates the identification of monolayer BP, expediting more extensive research on and potential industrial applications of this material. Full article
