Luminescent properties of solid solutions in the PbF2–Euf3 system and lead fluoroborate glass ceramics doped with Eu3+ ions

Luminescent hybrid materials based on organic phosphors and fluorides in the PbF2-LaF3 system

“…The crystal structure of HMs obtained by co-precipitation corresponds to the low-temperature rhombic modification of α-PbF2 (space group Pnma, contunite type), which is similar to the case with the deposition of nominally pure PbF2 from solution [13]. Solid-phase synthesis allows obtaining both a low-temperature α-PbF2 and a high-temperature cubic -PbF2 (space group Fm3m, fluorite type).…”

“…The synthesis was carried out by co-precipitation from aqueous solutions [6,9,13,16]. The starting materials were lead nitrate Pb(NO3)2 (99.99 wt%, Khimmed Group), lanthanum nitrate La(NO)3×6H2O (99.99 wt%, LANHIT Ltd.), ammonium fluoride NH4F (TECH System Ltd.).…”

Optical Properties Transformation under Laser Treatment of Hybrid Organic–Inorganic Thin Films

“…The observed changing of the luminescence color of the PbF 2 ‐based structure in the form of bright dots (Figure S8, Supporting Information) can be explained as follows. It is known that cubic β‐PbF 2 could dissolve dopants and form phosphors while α‐PbF 2 due to cell structure restrictions does not appear as a luminescent matrix . According to the study of HM (Alq 3 /PbF 2 /B 2 O 3 ) an exchange reaction between Alq 3 and PbF 2 was proceeded, in which the [Pb(q)F] 2 complex was presumably formed .…”
