Organic/Inorganic cluster salt for non-doping pure red electroluminescent devices

The salt of the organic/[Zn4(SPh)10]2− cluster was synthesized and used as a rare host emitter in non-doped red OLEDs. The devices based on it emit in the red region with a maximum wavelength of 630 nm and the emission peak was so narrow that the full width at half maximum (FWHM) is only about 80 nm.
