Oksifluorīdu sktikli stikla keramikas luminiscence retzemju joni Fizika

description

Darbā aprakstīta ar retzemju joniem aktivētu oksifluourīdu stiklu un stiklu keramiku luminiscence, un tiek apskatītas to izmantošanas iespējas baltās gaismas iegūšanai. Darba gaitā tika sintezēti oksifluorīdu stikli, aktivēti ar Eu3+ un Gd3+ joniem, un no tiem iegūtas stikla keramikas, izmantojot karsēšanas metodi. Paraugiem veikta DTA un XRD analīze, uzņemti luminiscences emisijas un ierosmes spektri, kā arī luminiscences dzišanas kinētikas. Darba gaitā no mērījumu rezultātiem tiek izdarīti secinājumi par retzemju jonu iebūvēšanos kristāliskās struktūrās, un luminiscences izmaiņām atkarībā no stikla keramiku karsēšanas temperatūras. Dažiem paraugiem novērotas platas Eu2+ emisijas joslas, kas nodrošina baltās gaismas emisiju, izmantojot UV ierosmi. Darbs rakstīts latviešu valodā, satur 55 lapas 28 attēlus un 10 tabulas.
