A novel near-infrared phosphor Mg₂InSbO₆:Cr³⁺ with high quantum efficiency and considerable persistent luminescence duration

Abstract

A series of novel non-gallate near-infrared (NIR) Mg2InSbO6:Cr3+ phosphors were successfully prepared using the solid-state reaction method. With the strong crystal field, the double-perovskite oxide Mg2InSbO6:Cr3+ under ultraviolet (UV) excitation...

Research progress of perovskite long afterglow materials

“…92 The NIR (698 nm) of Mg 2 InSbO 6 :Cr 3+ continued to emit light for more than 24 h after excitation by 365 nm UV light. 93 These materials all show excellent afterglow properties, and thus are worthy of further study.…”

Enhanced NIR optical properties of a single-site-occupied ultra-broadband InNbTiO6:Cr3+ phosphor at 965 nm through Ga3+ doping

“…The NIR spectrum corresponds to the characteristic absorption bands of X–H (X = C, N, O), offering rich structural and compositional information, making it highly suitable for analyzing the composition and properties of organic substances. 5–9 To effectively analyze the chemical components in a scanned object, the NIR spectrum should ideally have a long wavelength and sufficient bandwidth. In addition, c-Si solar cells exhibit optimal spectral response to 900–1100 nm light, and its photoelectric conversion efficiency can be enhanced through NIR spectral conversion technology.…”

Ambient light stimulation enabling intense and long-lasting ultraviolet-C persistent luminescence from Pr3+-doped YBO3 in bright environments

“…[1][2][3] On the other hand, photostimulated luminescence (PSL), also known as optically stimulated luminescence (OSL), is defined as a special optical phenomenon in which the luminescence intensity can be enhanced when the pre-irradiated phosphors are subjected to a suitable light stimulus. [4][5][6][7][8][9][10][11] Upon monochromatic light illumination, the deep-trapped electrons that cannot be effectively thermally activated at room temperature can be photo-released to the conduction band and then recombined with the emitting center, resulting in intense PSL compared to the very weak or no light emission in darkness. [12][13][14][15][16] To date, PSL materials have been well studied and have great potential for exciting applications in many important fields owing to their unique luminescence characteristics, such as optical data storage, security encryption, biomedical science, etc.…”
