Abstract:
The use of two hydrogen-containing molecules with different functions (donor of hydrogen atoms and provider of proton surface diffusion) enables one to dramatically increase the photochromic sensitivity at hydrogen photoinjection in both films and bilayer structures of WO$_3$. Application of a bilayer structure of WO$_3$ films enables one to unambiguously prove the effect of proton diffusion on the photochromic sensitivity at hydrogen photochromism.
