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 ...

Thermoluminescence studies of Nd doped Bi4Ge3O12 crystals irradiated by UV and beta sources

Karabulut, Y.; Canimoglu, A.; Ekdal, E.; Ayvacikli, M.; Can, N.; Karali, T. (PERGAMON-ELSEVIER SCIENCE LTD, 2016)

Thermoluminescence (TL) glow curves of pure and rare earth doped bismuth germanate (BGO) were investigated under UV and beta radiation. The glow curves of pure BGO crystal present different patterns for both kinds of ...

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 ...

Cathodoluminescence Response From Sanidine Feldspar

Karabulut, Y.; Canimoglu, A.; Can, N. (TAYLOR & FRANCIS INC, 2013)

In the present study, cathodoluminescence (CL) providing information about surface rather than bulk material reveals blue and red emissions within the sanidine feldspar from the Eifel Mountains, Germany. The emission line ...

Visible to infrared low temperature photoluminescence of rare earth doped bismuth germanate crystals

Canimoglu, A.; Ayvacikli, M.; Karabulut, Y.; Karali, T.; Can, N. (PERGAMON-ELSEVIER SCIENCE LTD, 2016)

In this paper, the influence of a series of rare earth (Eu, Tm, Nd) and Cr ion doping on the optical properties of BGO was investigated by means of photoluminescence (PL) from visible to IR region in the 10-300 K temperature ...

Identification of heat responsive genes in cotton

Demirel, U.; Gur, A.; Can, N.; Memon, A. R. (ACAD SCIENCES CZECH REPUBLIC, INST EXPERIMENTAL BOTANY, 2014)

High summer temperature negatively affects cotton yield, and better understanding of genetic mechanisms of heat stress responses in cotton may facilitate development of new heat tolerant cultivars. We attempted to determine ...

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 ...

Radioluminescence and photoluminescence characterization of Eu and Tb doped barium stannate phosphor ceramics

Ayvacikli, M.; Canimoglu, A.; Karabulut, Y.; Kotan, Z.; Herval, L. K. S.; de Godoy, M. P. F.; Can, N. (ELSEVIER SCIENCE SA, 2014)

In this paper, we report on structural and optical properties of terbium and europium doped barium stannate phosphors (BaSnO3) synthesised by conventional solid state reaction method. We have studied those materials by ...

Solid state synthesis of SrAl2O4:Mn2+ co-doped with Nd3+ phosphor and its optical properties
