These crystals give the material its mechanoluminescent properties but are so small that they don&#8217;t notably affect the visual transparency of the glass.<\/p>\n<p>&#8220;Our work could help mechanoluminescent materials find widespread use in a variety of applications, including light-emitting product labels and security codes,&#8221; said Wondraczek. &#8220;It also ties in well with the International Year of Glass by demonstrating the wide versatility and unexpected properties of glassy materials.&#8221;<\/p>\n<p><b>A more practical material<\/b><\/p>\n<p>In addition to being difficult to form into various geometries, mechanoluminescent powders require extra processing steps such as encapsulation in a matrix material. To create a more practical material, the researchers turned to glass-ceramics.<\/p>\n<p>Glass-ceramics are a relatively new type of material that consists of a crystalline material embedded into a glass matrix. The crystals can be used to give these materials very specific properties while the glass matrix allows them to be shaped with many of the same processes used for glass.<\/p>\n<p>The researchers created the mechanoluminescent glass-ceramic by developing an exceptionally fast and stable crystallization process that allows the tiny ZGO crystals to precipitate homogeneously inside the glass after it has been shaped. They showed that the materials emitted light under mechanical stress by using the ball-drop test, a standard way of imparting a known impact force to a material. &#8220;We found that the mechanoluminescence response was reproducible and rechargeable and that it exhibited a direct correlation with the impact energy,&#8221; said Wondraczek.<\/p>\n<p>Now that they have demonstrated the material&#8217;s light-emitting properties, they plan to adapt the glass composition so that it can be formed into sheet-like objects, optical fiber and microscale spherical beads and then explore how these could be used in components and devices. They also aim to exploit other features commonly attributed to glass-ceramics\u2014such as thermal, chemical and mechanical stability\u2014to gain new functions from the glassy materials.<\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            Researchers prepare novel low-melting, nitrogen-containing, stannous chlorophosphate glass\n                                        <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                Jiangkun Cao et al, Mechanoluminescence from highly transparent ZGO:Cr spinel glass ceramics, <i>Optical Materials Express<\/i> (2022).  <a rel=\"nofollow noopener\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1364\/OME.459185\">DOI: 10.1364\/OME.459185<\/a><\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>                                                 <strong>Citation<\/strong>:<br \/>\n                                                 New glass-ceramic emits light when under mechanical stress (2022, July 26)<br \/>\n                                                 retrieved 26 July 2022<br \/>\n                                                 from https:\/\/phys.org\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2022-07-glass-ceramic-emits-mechanical-stress.html<\/p>\n<p>                                            This document is subject to copyright.
