Description

technical field

[0001] The invention relates to bismuth salt glass, in particular to a bismuth salt glass and a preparation method thereof. Background technique

[0002] Bi 2 o 3 , PbO and other heavy metal glasses with a content of more than 50% by mole fraction have attracted people's attention for many years due to their high refractive index, high dielectric constant and wide infrared transmission range. Systematic studies have shown that the phonon energy in this glass structure is low, and it is suitable as a parent material for rare earth luminescence, so this glass is considered to be one of the candidate photonic functional materials for improving the upconversion efficiency of rare earth (see previous Technology Daniel J. Coleman, Stuart D. Jackson, Paul Golding, Terence A. King. Measurements of the spectroscopic and energy transfer parameters for Er 3+ -doped and Er 3+ , Pr 3+ -codoped PbO-Bi 2 o 3 -Ga 2 o 3 glasses, J. Opt. Soc. Am. B 19(2002) 2927-2929...
