"lanthanide nanocrystals ideal for high-quality light emission due to precise color capabilities, but as insulators cannot conduct electricity effectively,.. overcome wrapping them in organic semiconductor ligands acting as intermediaries, capturing charge carriers from electric field exciting lanthanide ions inside which then emit bright, stable light... 76X more efficient, nearly 99% triplet-energy transfer (almost no energy loss), can output full spectrum/ changing color only requires changing lanthanide dopant... phone screens.
