Synthesizing and photoluminescence properties of Eu3+-doped germanate and Dy3+-doped silicate hosts

WOS:000445668900010The Eu3+-doped germanate (Mg4GeO6 and Ba2GeO4) and Dy3+-doped silicate (Li3SiO4) hosts were prepared by solid state reaction in this study. Dy3+-ion for Mg4GeO6 and Ho3+-ion for both Ba2GeO4 and Li3SiO4 were used as co-dopants for these systems. The heat treatments were performed with reference to the DTA/TG results. The repeated and increased heat treatments used for the systems, the single phase crystals determined by the powder x-ray diffraction (XRD) analysis. Thus, the Mg4GeO6 and Ba2GeO4 systems formed additionally, the Li3SiO4 system could not be formed or indexed for any phase. Considerable photoluminescence (PL) thermoluminescence (TL) results were achieved due to the transitions of the Eu3+-, Dy3+- and Ho3+-ions.Karamanoglu Mehmetbey University, Scientific Research Projects Commission (BAP), Republic of Turkey [18-M-14]The authors would like to thank Karamanoglu Mehmetbey University, Scientific Research Projects Commission (BAP), 18-M-14 in the, Republic of Turkey for its financial support
