中文摘要	nd3+ -codoped and al3+-nd3+-codoped high silica glasses have been prepared by sintering nanoporous glasses impregnated with nd3+ stop and al3+ ions. the judd-ofelt intensity parameters omega(2,4,6) of nd3+-doped high silica glasses were obtained and used to analyze aluminum codoping effects. fluorescence properties of nd3+-doped high silica glasses strongly depend on the al3+ concentration. while nd3+ ion absorption and emission intensities of obviously increase when aluminum is added to nd3+-doped high silica glasses, fluorescence lifetimes decrease and aluminum codoping has almost no influence on the radiative quantum efficiencies. this indicates that aluminum codoping is responsible for an anti-quenching effect through a local modification of rare-earth environments rather than through physical cluster dispersion.
