A white phosphor based on oxyfluoride nano-glass-ceramics co-doped with Eu3+ and Tb3+: Energy transfer study
Strontium fluoride nanocrystals doped separately with Ln3+ = Eu3+ or Tb3+ ions (95SrF2·5LnF2), as well as co-doped with both the ions (95SrF2·Eu4Tb) were synthesized for comparison. Then, glass-ceramics consisting of the mono-doped or di-doped SrF2 nanocrystals incorporated into amorphous silica (90SiO2·9.5SrF2·0.5Ln or 90SiO2·9.5SrF2·0.1EuF3·0.4Tb) were prepared by sol-gel procedure. The studied materials were characterized by...

Emission enhancement of Eu(III) and/or Tb(III) ions entrapped in silica xerogels with ZnO nanoparticles by energy transfer
W pracy przedstawiono rezultaty wpływu domieszkowania nanocząsteczkami ZnO kserożeli krzemianowych zawierających jony Eu(III)i/lub Tb(III). Wzmocnienie emisji w kserożelach zawierających Tb(III) następowało na skutek wymiany energii między jonami Tb i nanocząsteczkami ZnO. Wzmocnienia takiego nie zaobserwowano w przypadku jonów Eu. Zaobserwowano również kwantowy efekt rozmiaru w przerwie energetycznej ZnO.

Phage-Directed Synthesis of Photoluminescent Zinc Oxide Nanoparticles under Benign Conditions
Biological systems, especially bacteriophages and peptides, are an attractive green alternative to other known methods of nanoparticle synthesis. In this work, for the first time, bacteriophages were employed to synthesize a specific peptide, capable of producing nanoparticles (NPs). Derivatives of M13 bacteriophage exposing a ZnO-binding peptide (TMGA-LGLKWPV) on either pIII or pVIII phage coat protein were constructed and used...
