micro-crystals by heat treatment and introduction of Ag nanocrystals respectively
the luminescence properties of glasses are improved. However
after further heat treatment
the luminescence properties of glasses with Ag nanocrystals decrease. As Ag nanocrystals can lead to excessive crystallization of glasses during heat treatment process
the auxiliary electric field heat treatment method is applied to control the precipitation of Ag nanocrystals and micro-crystals. After auxiliary electric field heat treatment
more Ag nanocrystals are produced and the growth of micro-crystals is controlled
which lead to the improved luminescence properties of glasses.
