Novel and Highly Efficient Semiconductor-Based Light Sources

Dear Colleagues,

Progress in the development of light sources for different regions of the electromagnetic spectrum has been non-uniform, primarily due to the introduction of appropriate materials and technological advances. The near-IR region has seen tremendous development and has benefited the most efficient light sources today. Progress in visible light sources seems to be less steep, despite the numerous achievements of the last few decades. However, countless applications of visible wavelengths, ranging from lighting to visible light communication and biomedical applications, will greatly benefit from the progress made in the development of efficient light sources.

This Special Issue on “Highly-Efficient Visible Light Sources” offers to bring together the most recent research focused on practical and theoretical approaches for the further improvement of the efficiency of visible light sources. The topics of this Special Issue include but are not limited to the following:

• III-V semiconductor lasers and LEDs;
• LED efficiency droop: mechanisms and mitigation;
• UV light sources;
• New visible lasers and LEDs concepts and optimization;
• Defects and their effects on emission efficiency;
• Visible light sources via frequency conversion and efficiency;
• Visible light for biophotonics and emerging applications.

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. Applied Sciences 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 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.
