 note = {Effect of alkali halides on optical properties of Tm-doped chalcogenide glasses, (((Ge30(Se+S)70)91Ga9)100-x(Alkali Halide)x)100-y Tmy (where, x = 0～15 mol%, y = 0～1 at%, Alkali Halide = CsCl, CsBr, CsI, RbBr or RbI) were studied. All samples were amorphous in 5 mol% alkali halides additions but the homogenous glasses were containing with RbBr and CsI. The lifetime at the 1780 nm (3F4→3H6) band in RbBr and CsI containing homogeneous glass increased about 2 times longer compared with that in glass without alkali halides. The lifetime increased monotonously increasing with each alkali halide. The values of lifetime are influenced by the species of alkali halides. The ionic radius of halogen and alkali ions would be related to the coordination around Tm ions.},
