Low glass transition temperature (Tg) glass with a glass transition temperature of
less than 200 °C has received great attention due to its wide application in the fields of
science and technology such as glass-metal sealing, electronic packaging, photon
conversion and organic composite materials. In addition to the low glass transition
temperature, fluorophosphate glass combines the common advantages of phosphate
glass and fluoride glass, such as high coefficient of thermal expansion, perfect glassforming ability and excellent optical properties, which have attracted great interests.
Tin fluorophosphate glass having a lower Tg value can be obtained by the divalent tin
ions introduced into the fluorophosphate glass. At the same time, the tin ion has high
polarizability to the fluorophosphate glass, which can improve the chemical stability of
the glass. Tin fluorophosphate glass has gradually become a new star for the preparation
of high-performance hybrid materials in recent years because it is similar to the
polymer's unique network structure and low melting point characteristics which
contribute to blending with polymers; tin fluorophosphate glass has also opened up new
avenues as a packaging material for the field of white LEDs because of its low melting
point which is conducive to blending with commercial phosphors. However, most of
these studies are limited to their structure and physical properties, and there have been
few reports focus on the photoluminescence properties of tin fluorophosphate glass. In
this paper, the luminescence properties of tin fluorophosphate glass with low melting
point will be used as the mainline to carry out the research on the mechanism and
photoluminescence characteristics of its own undoped, rare earth ions and transition
metal ion doping and metal halide perovskite quantum dots in tin fluorophosphate glass,
which is expected to provide reference for the research and application of low melting
point tin fluorophosphate glass.
