“…However, there are relatively few studies on the luminescence characteristics of phosphors with SrLaAl3O7 as the host and single-doped Dy 3+ . Rare earth ion-doped phosphors play a vital role in plasma display panels (PDP), light-emitting diodes (LED) and solid-state lighting due to their numerous luminescence characteristics, which have attracted extensive attention from researchers [16][17][18][19]. As we all know, before preparing and researching a certain kind of doped phosphors, it is necessary to select the appropriate luminescent center and host material of the phosphor.…”

White phosphors of single-substrate SrLa1-xAl3O7: xDy 3+ (x=0.01~0.08) have been successfully prepared by the high-temperature solid-phase method and the results show the best sintering temperature is 900°C. The phase of the phosphors analyzed by X-Ray diffraction (XRD) shows that the doping of Dy 3+ essentially unchange the crystal structure of the matrix SrLaAl3O7. 3+ in the matrix is 0.05. SrLa0.95Al3O7: 0.05Dy 3+ phosphor exhibits white light emission under 347 nm excitation, chromaticity coordinates are (0.343, 0.364), and color temperature is 5109 K. These results reveal SrLaAl3O7: Dy 3+ is a great single doped white light phosphor which is suitable for daily lighting use. The morphology and energy spectrum of phosphors of SrLa1-xAl3O7: xDy 3+ were carried out with a field emission scanning electron microscope (FESEM). The concentration quenching effect of the sample comes from the exchange interaction between Dy 3+ , and the optimal doping concentration of Dy

“…Recently, glassceramics containing dysprosium oxides have been found in applications for several different purposes. Tm 3+ doped glasses have attracted much interest due to their important optical properties used in lasers, optical amplifiers, network formers, photonic devices and as infrared sensors [15][16][17][18]. The present work reports on the preparation and characterization of rare earth doped heavy metal oxide (HMO) glass systems for lasing materials.…”

Glass sample of Zinc Lithium Tungsten Sodalime Borotellurite: (35-x) TeO2:10ZnO:10Li2O:10WO3:10CaO:10Na2O:15B2O3:xTm2O3. (where x=1,1.5 and 2 mol%) have been prepared by meltquenching technique. The amorphous nature of the prepared glass samples was confirmed by X-ray diffraction. Optical absorption ,fluorescence and FTIR spectra were recorded at room temperature for all glass samples. Judd-Ofelt intensity parameters Ωλ (λ=2, 4 and 6) are evaluated from the intensities of various absorption bands of optical absorption spectra. Using these intensity parameters various radiative properties like spontaneous emission probability, branching ratio, radiative life time and stimulated emission cross– section of various emission lines have been evaluated
