Enhanced red emission from YVO4:Eu3+ nano phosphors prepared by simple Co-Precipitation Method

Preparation and photoluminescence properties of hydrothermally synthesized YVO4:Eu3+ nanofibers

“…imply strong interactions between the atoms, which mainly arise from the stretching and bending of the shorter metal-oxygen bonds within the anionic groups. All the observations made here are in good agreement with earlier published reports [24][25][26]. Photoluminescence spectrum (Horiba Synapse 1024 Â 256 pixels, size of the pixel 26 mm, detection range: 300) of the assynthesized YVO 4 :Eu 3 þ nanofibers was measured with excitation wavelengths of 325 nm at room temperature (Fig.…”

Orange-Reddish Light Emitting Phosphor GdVO4:Sm3+ Prepared by Solution Combustion Synthesis

“…e average grain size, D, was estimated by the Scherer equation, D Kλ/β cos θ, where K is a constant related to the shape of the crystallite and is approximately equal to unity, we used K 0.89 as in [19], λ is the X-ray wavelength (0.15405 nm), and θ and β are the di raction angle and full width at half maximum (FWHM, in radians) of the corresponding peak, respectively. e strongest peaks (2θ) from XRD were used to calculate the average crystallite size (D) in the GdVO 4 :Sm nanopowder.…”

Citric based sol–gel synthesis and luminescence characteristics of CaLa2ZnO5:Eu3+phosphors for blue LED excited white LEDs

“…However, it generally degrades luminescent efficiencies due to the introduction of surface defects that act as non-radiative recombination sites. Therefore, phosphor synthesis techniques that can overcome the disadvantages of hightemperature solid-state reaction method are of great importance [18,19]. Here, we have adopted citrate based sol-gel method which is a simple, economical and yet an effective method for preparing luminescent materials, because it offers many advantages like high purity, relatively lower sintering temperature and in a much shorter sintering time.…”
