Abstract
Thin films of LiyV2O5 (0<y4. X‐ray diffractometry showed an orthorhombic structure that varied from nanocrystalline (n‐X ) for unheated substrates to polycrystalline (p‐X ) for substrates at 180 °C. Optical absorption was measured at 0.3<λp‐X LiyV2O5 and appeared blue‐shifted in proportion with y for n‐X Liy V2O5. At λ>0.5 μm there are absorption peaks associated with V4+ ions both for p‐X and n‐X materials, and a broad absorption feature for p‐X Liy V2O5 that is tentatively ascribed to electron hopping in the crystallographic b direction. The absorption goes up for increased y, as expected from the higher V4+ density.This publication has 40 references indexed in Scilit:
