The invention teaches electrospun light-emitting fibers made from ionic transition metal complexes ('iTMCs') such as [Ru(bpy)](PF)]/PEO mixtures with dimensions in the 10.0 nm to 5.0 micron range and capable of highly localized light emission at low operating voltages such as 3-4 V with turn-on voltages approaching the band-gap limit of the organic semiconductor that may be used as point source light emitters on a chip.

A cascaded light emitting device. The cascaded light emitting device includes: a base electrode formed of a base electrode material and electrically coupled to a base voltage lead; a top electrode layer formed of a top electrode material and electrically coupled to a top voltage lead; a number of electroluminescent layers arranged between and electrically coupled to the base electrode and top electrode layer; and at least one middle electrode layer formed of a middle electrode material. Each of the middle electrodes is coupled between two juxtaposed electroluminescent layers. The electroluminescent layers include a mixed conductor that luminesces with a peak wavelength.
