## Abstract KYF~4~/Yb^3+^, Er^3+^ nanocrystals with a mean diameter of approximately 13βnm were synthesized at 200βΒ°C in the high boiling organic solvent __N__β(2βhydroxyethyl)ethylenediamine (HEEDA). The particles crystallize in the cubic phase known from __Ξ±__βNaYF~4~ and form transparent colloid
