20.500.12556/RUL-106023 Green upconversion in Y2O3 :Yb nanopowder Green emission lines, in addition to the blue and the red, were observed upon 980 nm excitation in yttrium oxide (Y2O3) nanopowder codoped with Yb3+ and Tm3+, synthesized by the chemical combustion method. Upconversion emission studies suggest that the number and characteristics of the green lines are influenced by the annealing temperature as well as by the Yb3+/Tm3+ concentration ratio, opening possibilities for new customized applications. The chromaticity properties of the upconversion spectra were quantified by the Commission Internationale de l'éclairage coordinate analysis. upconversion luminescence optical properties nanophosphor fluorescence spectroscopy nadkonverzija luminiscenca optične lastnosti nanofosfor fluorescenčna spektroskopija CIE koordinate true false true Angleški jezik Slovenski jezik Članek v reviji 2019-01-16 09:34:29 2019-01-16 09:34:31 2025-03-06 11:00:06 0000-00-00 00:00:00 2015 0 0 Str. 1-12 no. 1 Vol. 9 Sep. 2015 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 535:62-492-026.771(045) 1934-2608 10.1117/1.JNP.9.093054 14175259 RAZ_Horvat_Darja_i2015.pdf RAZ_Horvat_Darja_i2015.pdf 1 BEEAC0EC7A5066DA66F821326943CBBE 3b67400ba9f7748de58705239a88aaf5fc93a0c7b45116be1cd6a3f363a25c18 42f1c304-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=116733 http://nanophotonics.spiedigitallibrary.org/article.aspx?articleid=2442453#Experimental 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=116732 Fakulteta za strojništvo 0 0 0
