Problems in the thermal investigation of the BaF2-YF3 system

Upconversion Luminescence Properties of Pr3+-Doped BaYF5 Nanoparticles Prepared by Microwave Hydrothermal Method

“…There are several articles in the literature devoted to the optical properties of BaYF 5 doped with Yb 3+ , Ho 3+ , Er 3+ , and Tm 3+ . − Although the photoluminescent and radioluminescent properties of transparent glass ceramics containing BaYF 5 :Pr 3+ nanocrystals have been studied, Karbowiak and Cichos and Fedorov et al question the existence of BaYF 5 . Indeed, the BaF 2 –YF 3 phase diagram does not feature the BaYF 5 compound, and one can expect the formation of a Ba 0.5 Y 0.5 F 2.5 solid solution. , Since BaYF 5 is more widely known in the literature, we decided to use this formula instead of Ba 0.5 Y 0.5 F 2.5 .…”

Synthesis and Structural Probing of Eu3+ Doped BaYF5 Nano‐Crystals in Transparent Oxyfluoride Glass‐Ceramics

“…As a bulk single crystal, Er 3+ and Yb 3+ :BaYF 5 is an excellent up‐converting material and has been shown to be eight times more efficient than LaF 3 :Er 3+ ,Yb 3+ . The investigations related to the synthesis of these fluoride crystals are mainly focused on the bulk crystals of BaYF 5 , BaY 2 F 8 , and non‐stoichiometric single crystals which are difficult and expensive to synthesize . Another alternative way for the synthesis of these fluoride polycrystalline powders in nano‐scale is the solution‐based hydrothermal method or thermal decomposition method .…”

Combustion synthesis of YAG:Ce phosphors via the thermite reaction of aluminum

“…formation [28]. The phase diagram of BaF 2 and YF 3 clearly reveals that the melting point of this mixture is decreased to below 950 °C [29]. Owing to this decreased melting point, it was predicted that the liquid phase of YAG and flux would be stable around 1000 °C, as shown in Fig.…”
