Additionally, a 75% strength increase of the KPAS glass was measured after abraded specimens were aged for 100 days in humid air relative to specimens which were tested immediately following abrasion.

However, due to its susceptibility to environmental factors, its research and application have been hampered. Recently, perovskite nanocrystals (PNCs) have been precipitated inside glass by using thermal treatment or femtosecond laser irradiation, which results in unprecedented stability because they are protected by glass matrix. This article reviews the fundamental structure and properties of PNCs, the benefits of perovskite nanocrystals-glass composite structure, and the current state of research into the use of a femtosecond laser to induce PNCs in glass. We also discuss the recent progress in the use of perovskite nanocrystals-glass composite structure for stereo-holographic computing, micro-LEDs and optical storage.</p></div>","PeriodicalId":37132,"journal":{"name":"Journal of Non-Crystalline Solids: X","volume":"18 ","pages":"Article 100182"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44511365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heating the glasses while pre-stressed with included water resulted in an even greater strength enhancement. The glasses with a higher concentration of structural defects in the dry glass have an expected lower dry-glass strength in comparison to the glass with fewer defects. However, the weaker dry glass shows a greater strength enhancement after pre-stressed water exposure caused by the increase in the silanol concentration in the more defective glass that offsets the otherwise weakened glass. Increased silanol concentration has been shown to increase the expansion of silica glass, creating an increased compressive stress on the pre-stressed-wet glass relaxed to original dimensions, allowing for an increased strength enhancement.</p></div>","PeriodicalId":37132,"journal":{"name":"Journal of Non-Crystalline Solids: X","volume":"18 ","pages":"Article 100191"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42081459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structure of these glasses has also been broadly investigated, but Raman studies are rare and current literature data shows a significant level of disagreements and discrepancies. Here we show that the source of this disparity is two-fold, first the low damage threshold of these glasses requires low photon energy and low power to obtain reliable spectra, and second the unusual surface oxidation of telluride glasses leads to strong Raman artefact in relatively short time. Overall, high resolution spectra of freshly polished glasses obtained at low power with a near infrared source reveal that only four main modes are required to consistently interpret all Raman spectral features. Analysis of these Raman spectra confirm the presence of large chemical disorder in Ge-As-Te and As-Te glasses, consistent with previously reported spectroscopic studies.</p></div>","PeriodicalId":37132,"journal":{"name":"Journal of Non-Crystalline Solids: X","volume":"18 ","pages":"Article 100186"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42939384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
