Synthesis and Optical Properties of Yb3 +/Er3 +, Yb3 +/Tm3 +, Eu3 + Doped NaLuF4, Na5Lu9F32, KLu3F10, and KLu2F7
Using a hydrothermal method and a co-precipitation method, hexagonal phase of NaLuF4, cubic phase of Na5Lu9F32, KLu3F10, and orthorhombic phase of KLu2F7 were synthesized. The cubic phase of Na5Lu9F32 were composed of spherical particles, and the hexagonal phase of NaLuF4 were composed of micro-rods. Also, the cubic phase of KLu3F10 were composed of nanoparticles, and the orthorhombic phase of KLu2F7 were composed of micro-hexagonal disks. With a 980 nm laser diode excitation, ultra-violet/green/red up-conversion emissions of Er3+ and ultra-violet/violet/blue/red up-conversion emissions of Tm3+ were recorded in Yb3+/Er3+ and Yb3+/Tm3+ doped NaLuF4 and KLu2F7. Under ultraviolet 393 nm or 395 nm radiation, the Eu3+ doped NaLuF4 and KLu2F7 showed orange light emissions. Yet the Eu3+, acting as a probe, demonstrated different asymmetric ratios (β) of the integrated intensity I(5D0 → 7F2) to that of I(5D0 → 7F1) in NaLuF4 and KLu2F7.
