“…The near-infrared region is divided into near-infrared short-wave NIR I (780-1100nm) and near-red longwave NIR II (1100-2526nm). Near infrared light has a potential application prospect in food quality detection, biological detection, biological imaging, and so on [1][2][3][4][5][6][7][8]. In recent years, the application of near infrared light in NIR phosphorescence conversion light-emitting diodes (pc-LED) has developed rapidly.…”

In this paper, the preparation of a series of Li 2 TiGe 1-x Cr x O 5 phosphors by high-temperature solid-state reaction is reported. The results of X-ray diffraction show that the doping of Cr 4+ ions makes the lattice expand to a larger size. X-ray photoelectron spectroscopy (XPS) analysis shows that the chromium ions in the sample are tetravalent, con rmed further by uorescence spectroscopy. Under the excitation of 980nm laser, the Cr 4+ ions 3 T 2 doped 3 A 2 radiates transition and emits light at 1300nm. At the same time, the luminescence lifetime decreases with the increase in Cr 4+ ions doping concentration. Li 2 TiGe 1-x Cr x O 5 phosphors have a broad application prospect in near-infrared LEDs. Highlights 1. The Li 2 TiGe 1-x Cr x O 5 phosphor was prepared by the high-temperature solid-phase reaction method.2. The luminescence lifetime decreases with the increase in Cr 4+ ions doping concentration.. 3. Li 2 TiGe 1-x Cr x O 5 phosphors have a broad application prospect in near-infrared LEDs..
