| 中文摘要 | fluorophosphate glasses with various content of al(po3)(3) were prepared. with the increment of al(po3)(3) content, density decreases while refractive index increases, and transition temperature, crystallization peak temperature and melt temperature increase which were suggested by differential scanning calorimetry. these glasses exhibit the best stability against crystallization with 7-9 mol'yo al(po3)(3) content. normalized raman spectra were used to analyze structure and phonon state. the increment of al(po3)(3) content does not affect phonon energy but results in the augment of phonon density. absorption spectra were measured. h-3(6) -> f-3(4) transition exhibits absorption at l band of the third communication window. compared with the energy of tm3+ excited states in other glass system, f-3(4) energy of tm3+ in these glasses is considerable higher and h-3(4) energy is considerable lower, and it can be predicted that emission band of h-3(4) -> f-3(4) transition is close to the amplified band of gain-shift tm3+ doped fiber amplifier. analyses of judd-ofelt theory suggest when al(po3)(3) content is no more than 7 mol%, judd-ofelt parameters omega(t) and the lifetime of h-3(4) energy level of tm3+ vary little with the increment of al(po3)(3) content, and when al(po3)(3) content is more than 7 mol%, omega(2) and omega(6) increase and radiative lifetime of h-3(4) energy level of tm3+ drops sharply with the increment of al(po3)(3) content.
