Synthesis Design and Properties of Ca5(BO3)3F: Bi3+/Eu3+: Insight into Luminescence, Temperature, and Pressure Sensing

“…It is common knowledge that host compounds are crucial to the luminescence process. Ca 5 (BO 3 ) 3 F (CBOF), as initially reported by Li et al, has been demonstrated to be an ideal host for luminescence because of its excellent chemical stability and extraordinary optical properties …”

“…Ca 5 (BO 3 ) 3 F (CBOF), as initially reported by Li et al, has been demonstrated to be an ideal host for luminescence because of its excellent chemical stability and extraordinary optical properties. 2 While CBOF has been recognized as a candidate material with excellent luminescence properties for some time, there has been limited exploration of its preparation methods, which typically involve high-temperature solid-phase techniques. 2 Ionic liquids are environmentally friendly solvents and reactants that possesses low vapor pressure, good thermal stability, and solubility to organic and inorganic compounds.…”

Anomalous intense emission of the 5D0/7F4 transition for reddish-orange light-emitting and fluorescent probe for multiple lattice sites in β-PbF2:Eu3+/K+ oxyfluoride glass ceramics

“…Alternatively, the 4f–4f transition of Eu 3+ is Laporte forbidden, leading to narrow emission spectra with little tunability. 23 According to the relationship between emission spectra and lattice structures, Eu 3+ can be applied as a spectral probe to investigate the roles of the charge compensation, 24 local structure, 25,26 and thermal effect of Ln 3+ -doped nanomaterials. 27,28 Generally, Eu 3+ ions are doped in the MeF 2 by substituting the Me 2+ ions due to their similar ionic radius.…”
