Mn2+–Mn2+ Magnetic Coupling Effect on Photoluminescence Revealed by Photomagnetism in CsMnCl3

“…The luminescence of CaZnOS:Mn 2+ red phosphor shows a redshift and shortened decay lifetime against increasing Mn 2+ amount . Additionally, a decrease of PL intensity and red shifting are also reported in some other Mn 2+ -doped sulfides and selenides like ZnS:Mn 2+ , CdS:Mn, ZnSe:Mn, etc. − Recently, the differences of Mn–Mn dipole–dipole interaction and spin-exchange interaction effects on modulating PL quenching of Mn 2+ emission have been discussed in a case of Mn 4 In 16 S 35 nanoclusters with well-controlled Mn–Mn distance . Introducing some heteronuclear ion, such as Cr 3+ , to magnetically couple Mn 2+ would be an option to shorten the Mn 2+ decay lifetime, but this inevitably introduces some unwanted emission peaks .…”

Construction of donor-mediator-receptor heterojunctions: Ni12P5/In(OH)3/CdIn2S4 ternary catalyst for photocatalytic hydrogen production

“…4c), respectively, which is consistent with the ref. 50. Moreover, the characteristic peaks at 161.63 and 162.91 eV corresponded to S 2p 3/2 and S 2p 1/2 of S 2− (Fig. 4d), respectively.…”

“…It can be seen from the figure that the crystallinity of CIS was low. 49,50 The peaks of the In(OH) 3 /CIS composites, which were 22.27, 31.70, 39.07, 45.43, 51.16, 56.45, 66.20, 70.79, and 75.261, corresponding to the (200), ( 220), ( 222), (400), (420), (422), (440), (442), and (620) planes of In(OH) 3 , respectively (JCPDS 85-1338), proved that In(OH) 3 was successfully loaded on the surface of CIS. For the Ni 12 P 5 /In(OH) 3 /CIS series of samples (Fig.…”

Ni12P5-Supported Marigold-Shaped CdIn2S4: A 2D/3D Non-Noble-Metal Catalyst for Visible-Light-Driven Hydrogen Production

“…Figure b shows the XRD patterns of Ni 12 P 5 , Ni 12 P 5 /CIS composites, and CIS. The diffraction peaks of CIS showed the characteristics of typical nanocrystals of CIS. , The main peaks of 32.72, 35.38, 41.74, 44.42, 46.96, and 48.96 corresponded to the (310), (002), (400), (330), (420), and (312) planes of Ni 12 P 5 , respectively (JCPDS no. 22-1190).…”

“…48 In Figure 4c, the peaks at 445.0 and 452.6 eV were assigned to In 3d 5/2 and In 3d 3/2 of In 3+ . 35,42 In addition, the characteristic peaks that appeared at 161.6 and 162.9 eV were attributed to S 2p 3/2 and S 2p 1/2 of S 2− (Figure 4d). 49 For Ni 12 P 5 , the binding energies at 855.6 and 873.2 eV for Ni 2p 3/2 and Ni 2p 1/2 of Ni x+ (Figure 4e), and the peaks at 860.8 and 879.1 eV belong to satellite peaks.…”
