Hydrothermal synthesis and lanthanide doping of complex fluorides, LiYF4, KYF4 and BaBeF4 under mild conditions

Abstract

The complex fluorides LiYF 4 , KYF 4 , BaBeF 4 and AYF 4 Eu x (A = Li, K) are hydrothermally synthesized at 140–240 °C and characterized by powder X-ray diffraction, thermogravimetric analysis, IR spectroscopy, scanning electron microscopy and luminescence measurements.
