Cy. Zhao et al., HYDROTHERMAL SYNTHESIS AND LANTHANIDE DOPING OF COMPLEX FLUORIDES, LIYF4, KYF4 AND BABEF4 UNDER MILD CONDITIONS, Chemical communications, (10), 1997, pp. 945-946
The complex fluorides LiYF4, KYF4, BaBeF4 and AYF(4)Eu(x) (A = Li, K)
are hydrothermally synthesized at 140-240 degrees C and characterized
by powder X-ray diffraction, thermogravimetric analysis, IR spectrosco
py, scanning electron microscopy and luminescence measurements.
