Presented herein are the important advancements in the development of a novel oxyfluoride GCS of the composition (SiO<sub>2</sub>-Al<sub>2</sub>O<sub>3</sub>)<sub>(100-a)</sub> (YLiF<sub>4</sub>)<sub>b</sub>: (YbF<sub>3</sub>)<sub>b</sub> (a = 35 and 40; in mol %, b = 1 and 2 mol%) with the corresponding parent glasses with an in-depth investigation on enhancing the optical performance for laser cooling. Depending on the oxide/fluoride (O/F) ratio and ytterbium content the internal quantum yield (iQY) varied between 70 and 99% in glass ceramics at several excitation wavelengths. The optical properties of GCs containing YLiF<sub>4</sub> and YF<sub>3</sub> nanocrystals obtained from the same initial composition (modulated by time and fusion temperature) were compared to find the optimal composition for optical refrigeration. Low fluorine content led to the generation of YLiF<sub>4</sub> as a major phase after ceramization and high fluorine content helped in the generation of the YF<sub>3</sub> phase. An increase in the radiative lifetime of YF<sub>3</sub> GCs compared to YLiF<sub>4</sub> GCs has been found to coincide with the enhancement of the PLQY, which is beneficial for laser cooling. The temperature change (ΔT) change measured using a fiber Bragg grating (FBG) in the glass and glass-ceramic samples with different pump wavelengths showed significant heat mitigation near ∼1030 nm. The observed enhanced PL intensity, iQY and lifetime after purification of YLiF<sub>4</sub> glasses imply that the purity of the material plays a paramount role in lowering the background absorption and enhancing the quantum yield. Looking ahead, we see a bright future for oxyfluoride GCs in applications requiring the ultimate levels of thermal, mechanical and optical performance, especially for the development of cryocooler devices, which are still technologically challenging and expensive. The usage of GCs will open up new possibilities in optical cooling technology, enabling cooling devices of any size and shape.</p></div>","PeriodicalId":37132,"journal":{"name":"Journal of Non-Crystalline Solids: X","volume":"17 ","pages":"Article 100173"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45713664","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}

Investigate the role of interatomic potential can be a fascinating method to study this myth from bottom up. In this work, molecular dynamics is used to systematically study the glass forming processes of binary CuZr melts on both structural and dynamical evolutions. The strong repulsion between Cu<img>Cu and the weak repulsion between Zr<img>Zr is found to determine the structural arrangement, and then affect the type, number and spatial correlation of clusters. The difference of melt dynamics is controlled by both the steep repulsion and the anharmonic attraction of potential. The increase of the anharmonic attraction in melts can also lead to a higher shear transformation zone density in the glass. Our findings provide deeper insights into the understanding of glass-forming processes and its connection to glassy performance controlled by interatomic potential.</p></div>","PeriodicalId":37132,"journal":{"name":"Journal of Non-Crystalline Solids: X","volume":"17 ","pages":"Article 100150"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49561954","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}
