摘要: In order to obtain new kind of glass ceramics (with improved mechanical strength, thermal and chemical resistance), oxyfluoride borosilicate (Si02-B203-Na20-LaF3) glass, containing Pr 3+ ions (0.82-0.41 wt% 2 O 3 ), has been melted then exposed treatment at 555 °C 620 °C. Changes in the absorption emission spectra fluorescence kinetics are observed analyzed. this work we report detail on results measurements along with interpretation which indicate an existence a nanocrystalline phase as result treatment.
