“…This resulted in formation of few about 2-3 nm sized nanoparticles inside the imprinted line of about 180 nm diameter. Identification of particles as mainly metallic Cu was confirmed in our previous work [41] through EELS and HRTEM. In addition, two peripheral black lines are produced on either side of the bright centre line as a result of this irradiation and this believed to be the accumulation of non-precipitated copper, migrated out of the centre line, which is the heaviest element in this glass.…”

Nanoprecipitation in different oxide glasses by means of electron irradiation in transmission electron microscopy (TEM) has been compared in this study. Upon irradiation, groups or patterns of nanoparticles with various morphologies and sizes were formed in borosilicate glasses, loaded with zinc, copper, and silver. The study successfully includes loading ranges for the target metal from doping level (1%) over medium level (20%) to majority phase (60%). It is found that particle patterning resolution is affected by parallel processes of amorphous phase separation, glass ablation, and delocalised precipitation. In addition, via an in-situ study, it is confirmed that by heating alone without irradiation, no precipitate nanoparticles form.

“…The shape of the impact region is, therefore, crater-like. More details on stationary irradiation of our Zn and Cu glasses have been reported in [26,41].…”
