“…Synthesis. GdVO 4 nanopowder doped with samarium ions was prepared by the solution combustion method, as described in [12,13] e prepared starting reagents were combusted with the ame burner at approximately 500°C, yielding a voluminous foamy powder in an intensive exothermic reaction. After the solution combustion synthesis, the nanopowder was annealed for 2 hours, in air atmosphere, at 900°C.…”

“…e morphology of nanopowders and the size of crystallites were determined by high-resolution scanning electron microscopy (SEM) equipped with a highbrightness Schottky eld emission gun (FEGSEM, TESCAN) operating at 4 kV. Photoluminescence (PL) studies reported in this work were performed using an optical parametric oscillator (Vibrant OPO), as described in [12,13]. e output of the OPO can be continuously tuned over a spectral range from 320 nm to 475 nm.…”

e gadolinium vanadate doped with samarium (GdVO 4 :Sm 3+ ) nanopowder was prepared by the solution combustion synthesis (SCS) method. After synthesis, in order to achieve the full crystallinity, the material was annealed in air atmosphere at 900°C. Phase identification in the postannealed powder samples was performed by X-ray diffraction, and morphology was investigated by high-resolution scanning electron microscopy (SEM). Photoluminescence characterization of the emission spectrum and timeresolved analysis have been performed using the tunable laser optical parametric oscillator excitation and the streak camera. Several strong emission bands in the Sm 3+ emission spectrum were observed, located at 567 nm ( 4 G 5/2 -6 H 5/2 ), 604 nm ( 4 G 5/2 -6 H 7/2 ), and 646 (654) nm ( 4 G 5/2 -6 H 9/2 ), respectively. e weak emission bands at 533 nm ( 4 F 3/2 -6 H 5/2 ) and 706 nm ( 4 G 5/2 -6 H 11/2 ) and a weak broad luminescence emission band of VO 4 3− were also observed by the detection system. We analyzed the possibility of using the host luminescence for two-color temperature sensing. e proposed method is improved by introducing the temporal dependence in the line intensity ratio measurements.

“…By adjusting the ratio of yellow to blue intensity, it is possible to obtain white light emission in Dy‐single‐doped phosphor . The investigations regarding the ratio of blue and yellow transition of the Dy 3+ ions indicate that the Dy‐doped YAG should be considered for the production of the white light emission . However, most reports about Dy‐doped YAG powders are used as thermographic phosphors due to its temperature sensitivity in the range of 295‐1973 K .…”

A kind of Dy‐doped yttrium aluminum garnet (YAG) transparent ceramic for ultraviolet excited single‐phase white light‐emitting phosphor was investigated, which has high‐quantum efficiency (45%). The temperature field of Dy:YAG transparent ceramic was calculated by steady‐state thermal simulation. Moreover, by combining with 365 nm light‐emitting diodes (LED) chip directly, the Commission Internationale de l’Éclairage coordinate (x = 0.33, y = 0.35) is close to the standard equal energy white light illumination. The Dy:YAG transparent ceramic, possessing of good optical and thermal properties, is promising for applications in high‐power LEDs devices.
