Cationic and oxygen vacancies in Sr2MgSi2O7 glass-ceramics
The aim of this proposal is continue to study oxygen and strontiun vacancies location and the environment in the crystalline phase Sr2MgSi2O7 obtained by two ways, from the glass-ceramic route and from aerodynamical levitation. On doping with Eu/Dy, the glass-ceramics are very efficient photoluminescence(PL) materials. The luminescence properties are also dependent on the temperature, which strongly indicates that oxygen vacancies play an important role in the still poorly understood luminescence mechanism. In order to optimize the composition of materials and their optical behavior, it is necessary to study further the different temperatures of the vacant environment of these glass ceramics.
