Description and Uses
Ammonium fluoride is employed in a new hydrothermal synthesis of complex flourides NaHoF4 and NaEuF4 these interesting compounds have the fluorite structure and are important for solid-state lasers as well as for photoluminescence and magnetic characteristics.
The product was used to prepare Ce3F nanoparticles (NPs) which were further conjugated to photosensitizers along with Au NPs to improve singlet oxygen generation in photosensitizers.
