“…Although some Cr 3+ -activated oxide phosphors [1,3,21,[25][26][27][28][29][30][31] have been reported, no detailed report on the Cr 3+ -activated Sr 3 Ga 2 Ge 4 O 14 -Sr 3 In 2 Ge 4 O 14 solid-solution system has been published to date. In this study, the NIR phosphor Sr 3 Ga 2−2x In x Ge 4 O 14 :0.03Cr 3+ (SGIGO:0.03Cr 3+ ) with higher emission intensity and better temperature stability was obtained via In 3+ -Ga 3+ cation substitution, and the luminescence performance of the phosphor was analyzed.…”

Cr3+-doped Sr3Ga2Ge4O14:0.03Cr3+ (SGGO:0.03Cr3+) phosphor was synthesized via a high-temperature solid-phase method. Considering the tunable structure of SGGO, Ga3+ ions in the matrix were substituted with In3+ ions at a certain concentration. The tuned phosphor produced a red-shifted emission spectrum, with its luminescence intensity at 423 K maintained at 63% of that at room temperature; moreover, the internal quantum efficiency increased to 65.60%, and the external quantum efficiency correspondingly increased to 21.94%. On this basis, SGIGO:0.03Cr3+ was encapsulated into a pc-LED, which was applied in non-destructive testing (NDT) experiments, successfully realizing the recognition of water and anhydrous ethanol, proving its potential application in the field of NDT.

Near‐infrared light sources have potential applications in many fields. Cr3+ is a good luminescence centre to prepare near‐infrared phosphors. Improving the performance of existing near‐infrared luminescent materials has indeed attracted great interest from researchers. The luminescence properties of Zn2TiO4:Cr3+ were improved by crystal field engineering strategies. Zn2+–Ti4+ was partially replaced using a Li+–Nb5+ ion pair based on the Zn2TiO4:Cr3+ phosphors. Luminescence Cr3+‐activated luminescent materials are sensitive to changes in the local crystal structure and crystal field environment. Doping of Li+–Nb5+ increased the luminescence intensity up to 2.7 times that of the undoped sample. Also, the thermal stability of the phosphor was greatly increased by the replacement of Li+–Nb5+.
