Abstract: Multi-layer nanocrystalline Ca (nc-Ca) films were prepared by vacuum evaporation method, using three different materials as the substrate, namely CaF₂(111), Si(100), and Si(111). The films can be stored in the air for a long time, and there was no obvious shedding phenomenon at room temperature. Nc-ca thin films on different substrates were characterised by XRD analysis, showed (111) preferred orientation. On CaF₂(111), Si(100) and Si(111) substrates, the average grain size of calcium are 36.8 nm, 43.9 nm and 45.2 nm, respectively. By SEM analysis, there was a better surface morphology of the films on the CaF₂(111) substrate.
