对表现出更高性能的红外材料的需求仍在增长;在热和机械方面以及光学窗口的宽度上，向长波长区域延伸透明度以满足空间应用的要求。玻璃和玻璃基陶瓷具有独特的流变性能，可用于成型和纤维拉伸。在控制由碱金属卤化物改性的硫属化物玻璃中的成核/生长过程中，已经有可能开发出含有纳米尺寸晶粒并且在中红外透明的新一代玻璃陶瓷。为了对宇宙进行光学探测，需要在20μm及以上区域透明的新的低声子玻璃，并且为了实现这一目标，开发了一种新的碲化物玻璃家族，其将Te与Ge结合，并添加镓或碘用于稳定。这种新型光学玻璃在2 ~ 20μm范围内是透明的，可以拉制成光纤。
The demand for infrared materials which exhibit higher performance is still growing; both on the thermal and mechanical side as well as on the width of the optical window, with an extension of the transparency towards the long wavelength region to satisfy the requirements of space applications. Glasses as well as glass-based ceramics offer the advantage of unique rheological properties allowing molding and fiber drawing. In controlling the nucleation/growth process in a chalcogenide glass modified by an alkali halide, it has been possible to develop a new generation of glass ceramics containing nanosize grains and transparent in the mid infrared. For the optical exploration of the universe, new low phonon glasses transparent in the 20μm region and beyond are needed and to reach this goal a new family of telluride glasses was developed in combining Te with Ge with the addition of Gallium or Iodine for stabilization. These new optical glasses are transparent from 2 to 20μm and can be drawn into fiber.
