Abstract

original image

Selektives Wachstum: NaYF4 bildet mit NaCl keine Kern-Schale-Strukturen, sondern wächst an den acht Ecken der NaCl-Nanowürfel, was zu einer Acht-in-eins-Käfigstruktur führt. Nach Dichtfunktionalrechnungen wird die Flächenselektivität durch die Grenzflächenenergie bestimmt, die sich wiederum aus dem Anionenzwang und der Koordinationszahl der Grenzflächen-Y3+-Ionen ergibt.
