Formation and Properties of GeSe2–Ga2Se3–PbI2 Novel Chalcohalide Glasses
The glass-forming region of the GeSe2–Ga2Se3–PbI2 system was determined and homogeneous glasses were prepared. The maximum dissolvable PbI2 can be up to 50 mol%. The structures of glasses were characterized by Raman spectroscopy. The thermal, optical, and some basic physical properties of the glasses were investigated. The results show that GeSe2–Ga2Se3–PbI2 glasses have a wide region of transmission window (0.7–16 m) and high refractive index (∼2.5) with the addition of PbI2. The glasses have good glass-forming ability and high glass transition temperatures. Consequently, these novel glasses may be promising candidate materials for infrared optics and nonlinear optical field.
