Abstract
This work highlights the high-pressure induced site swapping and improved ordering of Eu<sup>3+</sup> in La<sub>2</sub>Hf<sub>2</sub>O<sub>7</sub>:Eu<sup>3+</sup> nanocrystals which leads to red-orange-yellow tunable emission at low-moderate-high pressure regime and enhanced correlated color temperature.
