• Glass ceramics
• Europium doping
• Acoustic microscope
• Fracture toughness
• Micro-indentation
• Young's and shear moduli

Young's and shear moduli were analyzed in Eu(2+)-doped fluorozirconate glasses, which were additionally doped with chlorine ions. Upon annealing between 240 degrees C and 290 degrees C, barium chloride nanocrystals were formed in the glass. Determination of the Vickers hardness, H, leads to a slight trend of decreasing hardness for higher annealing temperatures, whereas subsequent annealing has almost no effect on the fracture toughness K(1c).
