Abstract
Maģistra darbā aprakstītas dažādas stroncija aluminātu sintēzes metodes un stroncija aluminātu fāzes. Veikta stroncija aluminātu sintēze ar šķīduma–degšanas metodi, par degšanas aģentiem izmantojot organiskas vielas un par dopantiem – dažādas koncentrācijas eiropiju un disproziju. Sintezēto vielu kvalitatīvā analīze veikta ar pulvera rentgendifraktometriju, noteikta īpatnējā virsma un mētīta fotoluminiscence.
Different synthesis methods of strontium aluminates and strontium aluminate phases were described. Strontium aluminate phosphors were prepared by the solution – combustion method using different organic compounds and different concentration of europium and dysprosium. X-ray powder diffraction measurements, specific surface area and measurements of photoluminiscence were performed.
