Hexagonal-phase NaREF<sub>4</sub> upconversion nanocrystals: the matter of crystal structure
Rui Shi, Carlos D. S. Brites, Luís D. Carlos
Abstract
The debates on the crystallographic details of the hexagonal phase of NaREF 4 (RE = rare earth elements) are reviewed, and a fresh perspective is proposed to understand the superior luminescence properties of the materials.
