| contents | The growth, structure and optical properties of CsI-PbI2 co-evaporated thin films F. Somma M. Nikl K. Nitsch C. Giampaolo A.R. Phani S. Santucci Física, Astronomía y Matemáticas The structure and optical properties of thin films grown by vacuum co evaporation of CsI and PbI2 powders from two independent crucibles were studied. Typical thickness of the grown films was about 0.5 micrometer. X-ray diffraction spectroscopy using different grazing angles (0.10-20) revealed the formation of ternary phases, namely CsPbI3 and Cs4PbI6 and gave us an estimate of their percentage in volume. The sizes of the aggregates were estimated by the Warren- Aberbach method in around 20-40 nm. A direct observation of the thin film surface by atomic force microscopy was performed. Absorption and luminescence spectroscopies were employed to characterize the optical properties of these ternary nano-aggregate phases in the 4.2 - 300 K temperature ranges 1999 artículo científico 1665-3521 https://www.redalyc.org/articulo.oa?id=94200916 en http://www.redalyc.org/revista.oa?id=942 Superficies y vacío application/pdf Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C.
