Phosphors Based on Rare Earth and Transition Metal Ions Doped Crystals

Dear Colleagues,

Dielectric and wide band semiconductors crystals doped with Rare Earth and Transition Metal Ions, due to unique spectroscopic properties, are used as phosphors. The broad use of phosphors started in the 1940s. They were introduced in the form of polycrystals in fluorescent tubes. Indeed, a new era of lighting has begun; thus far, all light sources invented by man mainly generate heat. Construction of the blue LED was another important progress that was achieved. Modern light sources may reduce the cost of lighting to the levels not previously imaginable and new features, thus far not common, are now accessible. By applying phosphors, we are, for the first time, in the position of creating light, which may mimic sunlight. Thus, for the first time, it is possible to drive human circadian rhythms, hormone production, and, consequently, health.

Moreover, based only on phosphors, light sources may be adjusted to specific purposes; for instance, in horticulture, since plants need only a specific part of solar radiation. Phosphors are also important in many other fields, such as medicine, or in the protection of valuables or for anti-counterfeiting measures. The list of phosphors and their application is large; there are long lasting or persistent phosphors, storage phosphors, or phosphors that may improve quantum efficiency of solar cells, both polycrystalline and monocrystalline phosphors are used for X-ray and gamma detection, and, last but not least, exists phosphors high Quantum Efficiency higher than 100%.

We invite investigators to submit papers, which discuss the development of phosphors. The potential topics include, but are not limited to:

• Modeling of phosphors.
• Property characterization and their relationships to external conditions, such as pressure , temperature, etc.
• Advances in development of phosphors.
• Reliability and stability of the phosphors including aging, temperature and UV and VUV excitation, etc.
• Phosphors for improvement of solar cells efficiency.
• Phosphors for detection of high energy radiation
• Applications of phosphors and prototype demonstration.

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. Crystals 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 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.
