Simultaneous Measurement of Electron and Ion Transfer in All-Solid Ion-Transfer Device Made of Transition Metal Cyanide Films

Abstract

The state-selective dissociation dynamics for anionic and excited neutral fragments of gaseous SiCl 4 following Cl 2p and Si 2p core-level excitations were characterized by combining measurements of the photoninduced anionic dissociation, x-ray absorption and UV/visible dispersed fluorescence. The transitions of core electrons to high Rydberg states/doubly excited states in the vicinity of both Si 2p and Cl 2p ionization thresholds of gaseous SiCl 4 lead to a remarkably enhanced production of anionic, Si − and Cl − , fragments and excited neutral atomic, Si * , fragments. This enhancement via core-level excitation near the ionization threshold of gaseous SiCl 4 is explained in terms of the contributions from the Auger decay of doubly excited states, shake-modified resonant Auger decay, or/and post-collision interaction. These complementary results provide insight into the state-selective anionic and excited neutral fragmentation of gaseous molecules via core-level excitation.

An Electrolyte-Free Thermo-Rechargeable Battery Made of Prussian Blue Analog Thin Films

“…Nano spaces within the framework enable the reversible storage of guest species (Na + and H 2 O) [15,16]. This property of M-PBAs results in various functionalities, such as lithium/sodium/potassium ion secondary batteries , tertiary batteries [5][6][7][8][9][10], electrochromism [46][47][48][49][50][51][52][53], and so on. Shibata et al [48] reported that an all-solid-state ion transfer device, in which only Na + ions but not electrons can pass through the interface, for electrochromic devices can be fabricated with the physical junction of two PBA thin films.…”

Na+ diffusion in Na x Co[Fe(CN)6]0.90 film as investigated by transmission image

“…To make a stepwise distribution of x, we performed initial oxidization process of the NCF90 film. Shibata et al 37) reported that the contact area of two PBA thin films in the air is permeable to Na + but not to electrons. Therefore, we contacted the left half of the NCF90 thin film with a preoxidized NCF90 film (x = 0.0) film with a thickness of 0.92 μm.…”
