Figure 3From: Distribution of Nd3+ ions in oxyfluoride glass ceramicsHigh-resolution TEM micrographs with marked interplanar distance d values of (a) GCs and (b) NCs. The insets are the simplified models for GCs and NCs, where the large white spheres stand for β-PbF2 nanocrystals, and small black spheres in GCs are for Nd3+ ions.Back to article page
