XPS analysis and luminescence mechanism of white SrZn2(PO4)2:Eu2+,Mn2+ phosphor with In3+ sensitizer

Development of an intense yellow-coloured BiVO4/ZrO2composite coating for anticorrosion multifunctional cool roofing

“…2e shows the spectra for Zn 2p, with the peaks at 1022.4 and 1045.7 eV corresponding to the Zn 2p 3/2 and Zn 2p 1/2 of hopeite and ZnO, respectively. 32 The spectra of the P 2p 3/2 were deconvoluted into two broad peaks at 133.6 and 134.9 eV for PO 4 3− and HPO 4 − formation, respectively, 33 as shown in Fig. 2f.…”

Mn2+ doped SrSn(PO4)2 nanopowder for new novel LED material

“…DRS spectrum of Mn 2+ doped STP is shown in figure 9. Several free ion terms are available for the transition metal ion Mn 2+ in the [Ar] 3d 5 configuration including 6 S, 4 P, 4 F, and 4 G. 6 S is put in ground state and subsequently separated to 6 A 1g . Visible region of the spectrum displays the four distinguishing bands at wavelengths of 380 (26309 cm −1 ), 420 (23803 cm −1 ), 470 (21271 cm −1 ), and 550 (18177 cm −1 ) nm.…”

“…The majority of the time, chemical preparation technique is used to create nanopowder including solution combustion, sol-gel, electrochemical, colloidal, capping and solid-state reactions. Among all the methods, the solid-state reaction approach is often used to produce nanoscale polycrystalline solid materials from a starting reagent combination [5,6]. At room temperature (27 °C), the initial reagents do not interact with one another in this method.…”

“…Strontium Tin Phosphate (STP) nanopowder was reported [28]. Several researchers studied Mn 2+ doped with rare earth co-doped phosphorus materials [6,18,19,23,25,29]. They exhibited different photoluminescence properties.…”
