AB  - In this investigation, samples of SrGd2O4 doped with different concentration of Yb3+ (2, 4, 6 at%) ions and constant concentration of Ho3+ (1 at%) were prepared. As for synthesis we chose combustion method assisted with glycine as a fuel and citric acid as a chelator. All samples were burned in the furnace at 500 °C for 1.5h and afterwards additionally thermally treated for 2.5 h at 1000 °C. X-ray diffraction (XRD) showed peaks that correspond to the pure orthorhombic lattice of SrGd2O4, space group Pnma (JCPDS Card No.:01-072-6387). FE-SEM micrographs revealed agglomerated phenomenon with spherical shape and diameter around 200 nm. Energy dispersive X-ray spectroscopy (EDS) verified uniform distribution of all constituting elements in particles. Powders optical characterization include measurement of up-conversion (UC) emission spectra after excitation at 980 nm, as well as up-converted intensity dependence on excitation power. Dominant green emission 5F4, 5S2 → 5 I8 was found in all samples, with the most intense emission with 2 at% of Yb3+ and dependence of intensity of UC emission on excitation power confirmed that green emission is facilitated by energy transfer mechanism with two photons.
