Effect of spin coating technique on mechanical properties of silicophosphate thin film doped by neodymium

Abstract

This work is focused on the effect of spin coating technique on the mechanical properties of silicophosphate (SP) thin films belonging to system SiO2-P2O5-Nd2O3. The thin films have been obtained by spin coating technique for three rotation speeds: 2000, 3500 and 5000 rpm. A soda-lime-silicate (SLS) glass was used as a substrate. Strength characteristics (Young modulus, E, hardness, H, and plasticity index, H/E) of the SiO2-P2O5-Nd2O3 films were determined by using the dynamical nano/microindentation under Pmax=10, 30, 50, 100, 900 mN. As a result of the fulfilled studies, it was drown a conclusion: new materials with regulable mechanical properties (elastic modulus, hardness, plasticity, brittleness) can be fabricated for practical applications.
