The Synthesis of Luminescent Glass-Ceramic Materials Activated with Europium Ions Using Silicon-Organic Compounds (Silicones)

Resumo

Luminescent materials, activated by europium ions, with the composition SrAl₂Si₂O₈/LaBO₃ were synthesized using organosilicon compounds (methyl polysiloxane MK). The luminescence properties in red and blue LED range are characteristic of materials synthesized at 1100°C. In addition, strong luminescence is characteristic of trivalent europium ions (peaks at 591, 616, and 655 nm) in the red region of the spectrum and weak luminescence in the blue region of bivalent europium ions (peak at 405 nm). The possibility of incorporating two types of europium cations (Eu²⁺ and Eu³⁺) into the structure of synthesized polycrystalline materials makes it possible to regulate their spectral properties as a function of the conditions of synthesis.
