Optical properties of zincfluorophosphate glasses doped with Dy3+ ions

The structure and optical characteristics of white-light nano-phosphors applied to LEDs

“…According to Medraj et al's research, the synthesis temperature of pure YAP phase is over 1500℃ [11]. In order to prevent the overgrowth of nanopowders and keep the optimal PL characteristic, the 1100℃ treatment temperature is chosen to synthesize the YAP:Dy [13,14,15]. The strongest absorption peak locates at 352 nm and this wavelength is chosen as the excitation wavelength for the PL measurements in this work.…”

Study on the Structural, Morphological and Optical Properties of RF-Sputtered Dysprosium-Doped Barium Tungstate Thin Films

“…Metal tungstates are prepared and characterized by different techniques such as thermal evaporation [4], electron beam evaporation [5],chemical vapour deposition [6], pulsed laser deposition [7,8] and RF magnetron sputtering [9]. Dysprosium is a suitable dopant for many inorganic lattices which produce white light emission by suitably adjusting the yellow and blue emissions [10]. In the present investigation dysprosium doped BaWO 4 films are prepared using RF magnetron sputtering technique and the structural, morphological and optical properties of the films annealed at a temperature of 700 °C are investigated using techniques such as X-ray diffraction (XRD), micro-Raman spectroscopy, field emission scanning electron microscopy (FESEM), atomic force microscopy(AFM) and photoluminescence spectroscopy(PL).…”

Tailoring the luminescence of Eu3+ co-doped Dy3+ incorporated aluminofluoro-borophosphate glasses for white light applications

“…Among the glasses, borophosphate glass possess combined advantages of both the borate [10,11] and phosphate glasses [12,13] such as good optical quality, higher thermal stability, large emission cross-section and narrow emission bandwidth [14]. Addition of Al 2 O 3 modifies the glass network due to the formation of new Al-O-P bonds instead of P-O-P, B-O-B and P-O-B bonds in the glass network [14].…”
