Special Issue Information

Dear Colleagues,

Defects in crystals may affect the mechanical, chemical and electrical properties of materials and are therefore subject to intense theoretical and experimental studies. Dislocations in the optoelectronic heterostructures act as non-recombination centres and may lead to device degradation. Vacancies may agglomerate into voids and affect the mechanical properties of crystals. The extended and point defects may be introduced for various reasons, which include the relaxation of mismatch strains in epitaxial structures, mistakes during the growth process or during post-growth treatment. The elimination of the defects is only possible when we understand the mechanisms of their introduction. This Special Issue of Crystals is devoted to theoretical and experimental studies of defects and successful methods of eliminating them. Authors are encouraged to submit their manuscripts covering the topics expressed in the keywords below.

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 papers will be 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 1400 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.

Study on Luminescence of KCl:Eu2+ Crystals after X-ray Irradiation at Room Temperature

Abstract
Bleaching with the F-light at the excitation bandpass of 20 nm results in the phenomenon that F-centre peak and thermoluminescence (TL) glow peaks due to Fz- and F-centres identically decrease with the F-bleach time, whereas TL glow [...] Read more.
Bleaching with the F-light at the excitation bandpass of 20 nm results in the phenomenon that F-centre peak and thermoluminescence (TL) glow peaks due to Fz- and F-centres identically decrease with the F-bleach time, whereas TL glow peak due to Fz-centre only remains almost constant irrespective of its time in the case of that at the excitation bandpass of 5 nm. Analysing the data on bleaching effects, absorption spectrum of X-ray irradiated KCl:Eu2+ crystal has a peak due to Fz-centre approximately within 20 nm of the wavelength 560 nm at F-centre peak. Electrons released from Fz-centres at 370 K and from F-centres at 450 K combine with Eu3+ ions, leading to the excited Eu2+ ions from which the luminescence at 420 nm is emitted. Full article
