Luminescent properties of R+ doped Sr2MgSi2O7:Eu3+ (R+ = Li+, Na+ and K+) orange–red emitting phosphors

Multicolor, Fluorescent Supercapacitor Fiber

“…For instance, red, orange, yellow, green, blue, and purple fibers are prepared by incorporation of corresponding colorful dye particles into MWCNT fibers ( Figure a). The spectrum peak of each color well matches the standard visible spectrum (Figure b; Table S1, Supporting Information) . Noting that strontium aluminate (SrAl 2 O 4 ), a chemically inert material in the dye adopted in this work, can convert energy from the ultraviolet illumination and transform them into longer wavelengths within visible light range, which offers indication function to the resulting devices in dark‐environment applications.…”

Structural and Optical Properties of Hydrothermally Synthesized ZnO and Zn0.99O:Eu3+ Powders

“…The broad emission band below 575 nm, corresponding to green emission, is attributed to the recombination luminescence of single-ionized oxygen vacancies [23]. Strong emission peaks are detected at 580, 592, 612, 653, and 705 nm, which originate from the transition of Eu 3+ ions from the 5 D 0 excited state to the 7 F J (J = 0, 1, 2, 3, and 4) ground state, respectively [24,25]. It is observed that the emission peak at 612 nm ( 5 D 0 → 7 F 2 ), corresponding to the red emission, is much stronger than that at 592 nm ( 5 D 0 → 7 F 1 ), corresponding to orange emission.…”

Spinodal Decomposition in Functionally Graded Super Duplex Stainless Steel and Weld Metal

“…One reason could be different levels of residual stresses in the as-received plates as this could significantly affect the kinetics of the phase separations. [27,28] The maximum hardness after arc heat treatment and percentage of maximum hardness increase are shown in Figure 11. The reason to use maximum hardness is to see the maximum changes that occurred in the FGMs compared to the condition prior to heat treatment.…”
