WebRespirable Crystalline Silica (silica) is identified as one of the Top 2 Chemicals which pose the greatest risk to workers in NSW (the other being Formaldehyde). Aligned to SafeWork NSW’s Roadmap for NSW 2024, this project aims to achieve a 30% reduction in serious injuries and illnesses by 2024, in relation to exposure to hazardous chemcials. WebSep 28, 2024 · We fabricated a Yb:YAG crystal-derived silica fiber (YCDSF) by the melt-in-tube method with a CO2 laser-heated drawing tower and explored the influences of the heat treatment method on fluorescent properties in the YCDSF. After the heat treatment, the intensity of the emission peaks and the fluorescence lifetime of the YCDSFs improved. In …
