Cathodoluminescence and Raman characteristics of CaSO4:Tm3+, Cu phosphor
Ekdal, E.; Garcia Guinea, J.; Kelemen, A.; Ayvacikli, M.; Canimoglu, A.; Jorge, A.; Can, N. (ELSEVIER SCIENCE BV, 2015)The physical characterization and phosphor emission spectra are presented for CaSO4 doped with Tm and Cu. All spectral wavelengths are related to electronic transitions of Tm3+ ions. The powder X-ray diffraction pattern ... -
Characterisation and luminescence studies of Tm and Na doped magnesium borate phosphors
Ekdal, E.; Garcia Guinea, J.; Karabulut, Y.; Canimoglu, A.; Harmansah, C.; Jorge, A.; Can, N. (PERGAMON-ELSEVIER SCIENCE LTD, 2015)In this study, structural and luminescence properties of magnesium borate of the form MgB4O7 doped with Tm and Na were investigated by X-ray diffraction (XRD), Raman spectroscopy and cathodoluminescence (CL). The morphologies ... -
Doping Sm3+ into ZnB2O4 phosphors and their structural and cathodoluminescence properties
Kucuk, N.; Bulcar, K.; Dogan, T.; Garcia Guinea, J.; Portakal, Z. G.; Karabulut, Y.; Can, N. (ELSEVIER SCIENCE SA, 2018)In this study, ZnB2O4:xSm(3+) (0.01 <= x <= 0.05 mol) powder phosphors have been synthesized by low temperature chemical synthesis method. The structure and morphological observation of the phosphor samples were systematically ... -
Solid state synthesis of SrAl2O4:Mn2+ co-doped with Nd3+ phosphor and its optical properties
Ayvacikli, M.; Kotan, Z.; Ekdal, E.; Karabulut, Y.; Canimoglu, A.; Garcia Guinea, J.; Can, N. (ELSEVIER SCIENCE BV, 2013)The optical properties of alkaline earth aluminates doped with rare earth ions have received much attention in the last years and this is due to. their chemical stability, long-afterglow (LAG) phosphorescence and high ... -
Structural and luminescence effects of Ga co-doping on Ce-doped yttrium aluminate based phosphors
Ayvacikli, M.; Canimoglu, A.; Muresan, L. E.; Tudoran, L. Barbu; Garcia Guinea, J.; Karabulut, Y.; Can, N. (ELSEVIER SCIENCE SA, 2016)Herein, we primarily focus on luminescence spectrum measurements of various types of green emitting yttrium aluminate phosphors modified with gallium (Y3Al5-xGaxO12) synthesised by solid state reaction. The luminescent ... -
Study of luminescence of Mn-doped CaB4O7 prepared by wet chemical method
Oguz, K. F.; Ekdal, E.; Aslani, M. A. A.; Canimoglu, A.; Garcia Guinea, J.; Can, N.; Karali, T. (ELSEVIER SCIENCE SA, 2016)In this study, manganese (Mn) doped Calcium Tetraborate (CaB4O7) samples were prepared by the wet chemical method. Under beta irradiated, CaB4O7:Mn showed thermally stimulated luminescence (TSL) glow peaks at approximately ... -
Tunable luminescence of broadband-excited and narrow line green emitting Y2SiO5:Ce3+, Tb3+ phosphor
Muresan, L. E.; Karabulut, Y.; Cadis, A. I.; Perhaita, I.; Canimoglu, A.; Garcia Guinea, J.; Can, N. (ELSEVIER SCIENCE SA, 2016)Cerium and terbium activated white emitting yttrium silicate phosphors (Y-2-x-yCe(x)Tb(y)SiO(5)) having average size between 96 and 123 nm were synthesised by a gel-combustion, and their phase and crystal structures, ...
