W pracy opisano nowe luminofory ceramiczne na bazie oliwinów germanianowych. Przeprowadzono charakterystykę strukturalną oraz optyczną związków Li2MgGeO4:Ln3+ (Ln = Pr, Ho, Tm) ze szczególnym uwzględnieniem widm emisji i diagramu chromatyczności CIE. Badania wykazały, że związki Li2MgGeO4:Ln3+ o strukturze oliwinu emitują światło w zakresie czerwonym (Pr3+), zielonym (Ho3+) i niebieskim (Tm3+). Wyniki eksperymentalne sugerują możliwość zastosowania materiałów ceramicznych Li2MgGeO4:Ln3+ jako emiterów światła widzialnego.

In this work, new ceramic phosphors based on germanate olivines are descibed. Structural and optical characterization of compounds Li2MgGeO4:Ln3+ (Ln = Pr, Ho, Tm) was carried out, with a special regards to emission spectra and chromaticity diagram CIE. The studies shown that Li2MgGeO4:Ln3+ compounds with olivine structure emit red (Pr3+), green (Ho3+) and blue (Tm3+) light. The experimental results suggest that ceramic materials Li2MgGeO4:Ln3+ can be used as an emitters of visible light.
