Structural, luminescent and in vitro studies of europium-doped soda lime phosphate glasses.

In this article, we have reported the effect of varying concentration of europium (Eu) in (50 - x)% P O -25% Na O-24% CaO-% Eu O , where x = 1, 3, 5. The glass samples were synthesised via conventional melt-quench method. The impact of europium ion (Eu ) on the structural, optical and luminescent properties of phosphate soda lime glasses has been studied using X-ray diffraction (XRD), Fourier-transformed infrared (FTIR) spectroscopy, ultraviolet-visible spectroscopy, scanning electron microscopy coupled with energy-dispersive spectroscopy and photoluminescent techniques.

Structural and luminescence studies of titanium co-doped SrY O :Eu phosphors.

Here, europium-doped (1 to 11 mol%) and titanium (1 to 5 mol%)co-doped SrY O :Eu phosphors were synthesized using solid-state reaction method. The synthesized samples were characterized using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy (FTIR), and photoluminescence (PL) techniques for structural, morphological, functional group, and photoluminescence studies, respectively. XRD patterns confirmed the formation of pure phase SrY O at 1300°C and structural parameters were further determined using Rietveld refinement.

White light emission and thermoluminescence studies of Dy -activated hardystonite (Ca ZnSi O ) phosphor.

Here, we report the photoluminescence and thermoluminescent properties of Dy-activated Ca ZnSi O phosphors synthesized using the solid-state method. The synthesized phosphors showed hardystonite type structure, and had micron-sized particles. Fourier transform infrared spectroscopy (FTIR) showed the existence of the functional groups and confirmed the formation of phosphor and photoluminescence techniques.

Short review on recent progress in Mn -activated oxide phosphors for indoor plant light-emitting diodes.

In the modern era, growing number of indoor plants for various purposes, such as vegetation, flowering, and decorations, has increased over the traditional follow-up trends for plantation. However, the indoor plantation requires different parameters for their growth; among these, light plays a significant role. In order to control the growth of plants using light-emitting diodes, Mn-doped oxide phosphors have emerged as promising candidates due to their broad and intense emission bands in the red and far-red spectral range.

Spectroscopic analysis of alkaline-earth metal (Mg, Ca, Sr and Ba) co-doped GdO:Eu phosphors synthesized via co-precipitation route.

This paper reports the effect of alkaline earth metals (AEM = Mg, Ca, Sr, Ba) co-doping on the structural, morphological and luminescent properties of GdO:Eu phosphors. The concentration of the Eu ions was fixed 4 mol% to avoid the chances of the concentration quenching. AEM co-doped GdO:Eu XRD profile confirmed the synthesis of cubic-phase of all the co-doped samples.
