Abstract

doped organic-inorganic materials were fabricated with ethyl silicate and 3-glycidyloxypropy-trimethoxysilane as precursors by sol-gel method. According to the Judd-Ofelt theory

the Judd-Ofelt strength parameters(

)were calculated in terms of the characteristics of the absorption spectra and the physical-chemical properties. Meanwhile

according to the McCumber theory

the absorption and stimulate emission cross-section corresponding to the

←→

(1.8 μm) transition of Tm

were also calculated. The gain cross section was calculated by using the emission cross-section

absorption cross-section and Tm

concentration. These Tm

-doped organic- inorganic materials would have a potential application in mid-infrared lasers at about 1.8 and 2.0 μm wavelength.
