From: Towards REPO4 nanocrystal-doped optical fibers for distributed sensing applications
Representative SEM micrographs of cross-sections for the YPO4 nanocrystal-doped optical fibers drawn from preform #3 at: (a) 1900 °C, (b) 1950 °C and (c) 2000 °C; (d) Mean cubic-shaped nanocrystal size vs drawing temperature, along with the standard deviation (σ) plotted as error bars; HRTEM and the corresponding SAED patterns (scale bars of 2 1/nm) for the three characteristics morphologies: (e) cubic-shaped, (f) rod-shaped and (g) rounded cubic-shaped nanocrystals.
