Abstract

This study aims to address the crystal non-uniformity in photo-thermo-refractive (PTR) glass by exploring the synergistic regulation of multiple physical fields in photo-thermo-induced crystallization processes through simulations and experimental validation. This study reveals that Ce^3 + doping concentration affects the attenuation gradient of the 325 nm light field, with 0.013 mol% identified as the optimal concentration for balancing light field penetration and photosensitive reaction. By optimizing the heating/cooling rate and forced convection rate, the internal temperature gradient of PTR glass can be well controlled. Under the moderate concentration of Ce³⁺ (0.013 mol%) doping and optimized thermal treatment parameters, small (40–60 nm) and density (1.2–1.8 ×10²⁰ m⁻³) NaF grains can be obtained in a large (75 mm × 75 mm × 2 mm) PTR glass, with the mass fraction fluctuating less than 0.05 wt%. These findings offer valuable insights for the fabrication of large and high-quality optical devices based on PTR glass.

光-热折射玻璃多物理场均匀性调整的有限元模拟与实验研究

本研究旨在通过模拟和实验验证，探索光热诱导结晶过程中多个物理场的协同调节，解决光热折射（PTR）玻璃的晶体不均匀性问题。研究表明，Ce3 +掺杂浓度影响325 nm光场的衰减梯度，确定0.013 mol%为平衡光场穿透和光敏反应的最佳浓度。通过优化加热/冷却速率和强制对流速率，可以很好地控制PTR玻璃内部温度梯度。在中等浓度的Ce3+（0.013 mol%）掺杂和优化的热处理参数下，可以在大尺寸（75 mm × 75 mm × 2 mm） PTR玻璃中获得小（40-60 nm）和密度（1.2-1.8 ×10²⁰m⁻³）的NaF颗粒，质量分数波动小于0.05 wt%。这些发现为基于PTR玻璃的大型高质量光学器件的制造提供了宝贵的见解。

期刊介绍： The Journal of the European Ceramic Society publishes the results of original research and reviews relating to ceramic materials. Papers of either an experimental or theoretical character will be welcomed on a fully international basis. The emphasis is on novel generic science concerning the relationships between processing, microstructure and properties of polycrystalline ceramics consolidated at high temperature. Papers may relate to any of the conventional categories of ceramic: structural, functional, traditional or composite. The central objective is to sustain a high standard of research quality by means of appropriate reviewing procedures.
