Synthesis and luminescence of Cs2HfCl6 micro- and Cs2HfF6 nanoparticles

Cs 2 HfF 6 (CHF) nano- and Cs 2 HfCl 6 (CHC) micro-particles were synthesised using wet chemical methods. The luminescence of CHC single crystals is replicated in the micro-particles, paving the way toward particle-based CHC phosphor materials.
