dc.description.abstractA difference in work function plays a key role in charge transfer between two materials. Inorganic electrides provide a unique opportunity for electron transfer since interstitial anionic electrons result in a very low work function of 2.4–2.6 eV. Here we investigated charge transfer between two different types of electrides, [Ca2N]+$e and [Ca24Al28O64]4+$4e, and single-walled carbon nanotubes (SWNTs) with a work function of 4.73–5.05 eV. [Ca2N]+$e with open 2-dimensional electron layers was more effective in donating electrons to SWNTs than closed cage structured [Ca24Al28O64]4+$4e due to the higher electron concentration (1.3 1022 cm3) and mobility (200 cm2 V1 s1 at RT). A non-covalent conjugation enhanced near-infrared fluorescence of SWNTs as high as 52%. The field emission current density of electride–SWNT–silver paste dramatically increased by a factor of 46 000 (14.8 mA cm2) at 2 V mm1 (3.5 wt% [Ca2N]+$e) with a turn-on voltage of 0.85 V mm1.-
