Lowering the melting point of ZIF via an anion competing effect in MOF hybrid glasses

hybrid glass exhibits an ultrahigh glass-forming ability (∼0.94) and high infrared transmittance approaching 60% within the range of 290 nm to 6 µm. The halide-induced eutectic strategy enables the low-temperature processing of molecular hybrid MOF glasses with promising optical performance, expanding the MOF glass family and advancing low-density infrared optics for lightweight sensing and imaging systems.
