Transparent glass ceramic (GC) films and self-supported layers of composition 80SiO2-20LaF3 doped with Nd3+ were prepared by sol-gel method for the first time. GC films were deposited by dip coating on different substrates and heat treated between 350-850 deg C for 1, 3 and 80 hours. The structural analysis of thin films was performed by GI-XRD and HR-TEM to check the LaF3 nanocrystals precipitation in the SiO2 matrix, revealing a crystal size lower than 5nm.
