本研究论文探讨了在非等温条件下，含有2摩尔% Ag2S系统的70GeS2-20In2S3-10CsI卤化玻璃的结晶行为。标题中的关键词“添加银”表明了实验的核心，即研究者们关注的是银作为杂质对玻璃结构和性能的影响。
研究主要集中在玻璃的结晶过程上，发现随着退火温度的升高，玻璃的透明度转变开始向更长波长区域移动。这种现象反映了温度对玻璃相转变为晶体相的影响，即温度是驱动结晶的关键因素。通过差示扫描 calorimetry (DSC) 测量，研究人员能够准确地获取到玻璃的热性质数据，包括结晶温度随温度变化的速率。
更为具体的是，他们计算出In2S3相的结晶活化能Ec值约为28倍于第二阶段的结晶活化能，这一显著差异表明，仅In2S3晶化的控制性结晶化过程在透明氧化物玻璃陶瓷中是可行的。这不仅提供了对材料设计的新见解，也为实现具有特定性能的玻璃陶瓷提供了可能。
此外，该研究还揭示了加热处理对玻璃硬度的显著提升。经过不同温度处理后，玻璃的硬度从最初的204 kg/mm²提高到了230.8 kg/mm²，这暗示着热处理可能作为一种有效的增强手段，用于优化玻璃的机械性能，使其在实际应用中更具耐久性和强度。
这篇论文深入研究了银对70GeS2-20In2S3-10CsI卤化玻璃的结晶行为及其对玻璃性能的影响，这对于理解此类复合玻璃的制备和优化过程具有重要意义，对于玻璃材料科学和工程领域具有实用价值。

beginning of transmission is shifted toward longer wave-
length as a function of annealing temperature. Thermal
properties were measured by the differential scanning
calorimeter. From the heating rate dependence of crystal-

tallization and the crystallization rate constant (K) were
calculated. The K value of 2.44 9 10

Introduction
Chalcogenide glasses have been studied intensively for
several decades because of their practical and potential
applications in the fields of infrared (IR) imaging,
chemical and biological sensing, optical communications,
infrared laser power delivery, and high-efficient host for
rare earth doping [1–4]. Tao et al. [5, 6] studied that the
Dy

-doped GaGaCdS glasses would be good potential
candidates of chalcogenide glass for lasers, amplifiers,
and high brightness sources in the near- and mid-IR
region, and the mechanical limitations of ChG fibers and
enables optimizing the optical properties for non-linear
applications. However, compared to oxide glasses, chal-
cogenide glasses have relatively weak mechanical prop-
erties with high thermal expansion coefficient and low
resistance to thermal shock, then the advantages of chal-
cogenide glasses have not been fully exploited. Fortu-
nately, it is well known that crystallization of glasses is a
good way to balance thermal expansion, restrain shock
sensitivity, and inhibit crack propagation [7, 8]. On the
other side, chalcogenides and halides have been used, and
reproducible glass-ceramics have been obtained with
excellent infrared transmission [9].
Currently, glass-ceramics are attracting interest due to
the improved mechanical properties, and kept an excellent
IR transmittance. For example, Zhu et al. [10] studied that
controlled crystallization of GeS
