Luminescent hybrid materials based on (8-hydroxyquinoline)-substituted metal-organic complexes and lead-borate glasses

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

“…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 . The similar complexes [Pb(q)I] 2 had been described by Najafi et al The PL spectrum of the complex is broadening comparing to that of Alq 3 (Figure ).…”

“…Bulk HM's could be fabricated by different pathways . It was demonstrated that the melting technique allowed synthesizing luminescent HM's by the proceeding of an exchange reaction between a coordinating organometallic phosphor and an inorganic low‐melting glass matrix …”

“…It has been established that during the synthesis at high temperature in melted inorganic glass an exchange reaction between organic ligands and metal ions of inorganic constituent have been proceeded . Bulk HM's based on inorganic glass matrix of the composition 80(mol%) PbF 2 – 20(mol%) B 2 O 3 and various organic phosphors complexes of 8‐hydroxyquinoline with I, II, and III groups metals of the Periodic Table and lanthanide phenanthroline complexes has been found to show efficient PL at phosphor contents about 0.1 wt% in the matrix. Partial HM's crystallization led to PL intensity increase in 1.5–5 times.…”

Synthesis and characterization of bis‐(8‐hydroxyquinoline) strontium (SrQ2) in water medium

“…In recent years, luminescent materials have become a hot issue in the field of material research; 8-hydroxyquinoline metal complexes have become a new show in the field of optical sensors 1,2 and organic light-emitting devices. [3][4][5] Since 1987, Tang et al applied 8-hydroxyquinoline aluminum to luminescent materials.…”

Stability constants of cerium(IV) complexes with 8-hydroxyquinoline and 8-hydroxy-7-iodoquinoline-5-sulfonic acid

“…The luminescent properties of REE complexes with 8-hydroxyquinoline and its derivatives are employed in luminescent analysis, technologies for creating materials with photo-and electroluminescent properties for optoelectronics, photonics, chemo-and biosensorics. 3,4 8-hydroxyquinoline is used in the extraction and spectrophotometric determination of cerium(IV), and cerium(IV) is employed in the oxydimetric determination of 8-hydroxyquinoline. 5 However, there are no data on the thermodynamic stability of cerium(IV) complexes with 8-hydroxyquinoline (HOxiN) and 8-hydroxy-7-iodoquinoline-5-sulfonic acid (H 2 Fer) in the literature.…”
