[1] Laser modification of luminescent hybrid materials based on lead oxyfluoride glasses and metal organic phosphors / O. B. Petrova, M. O. Anurova, R. R. Saifutyarov et al. // E-MRS 2017 Spring Meeting Strasbourg, France – May 22-26. — SYMPOSIUM X: New frontiers in laser interaction: from hard coatings to smart materials. — Strasbourg, France –, 2017. — P. X.P_1.1–X.P_1.1. Bulk hybrid materials (HM’s) based on inorganic glass matrix of the composition 80 (mol.%) PbF2-20 (mol.%) B2O3 and various organic phosphors (complexes of 8-hydroxyquinoline with I, II, III groups metals of the Periodic Table and lanthanide phenanthroline complexes) is established to show efficient photoluminescence (PL) at phosphor contents about 0.1 wt% in the matrix’s. Partial HM's crystallization led to the increase of PL intensities in 1.5-5 times. Local crystallization of HM's stimulated by femtosecond laser beam allowed to create 3D integrated optics elements. PbF2 crystallites formed inside HM had lower refractive index as compared to the glass matrix. HM-based samples with locally controlled PL were fabricated by Pharos SP laser (wavelength 1030 nm, pulse duration from 180 to 5000 fs, frequency repetition from 1 to 1000 kHz, maximum power 6 W). The samples demonstrated the increase in PL towards the initial HM's and waveguide effect in the laser-modified regions.
