Metal halide perovskites (MHPs) have recently attracted significant interest, owing to their excellent optoelectronic properties and diverse applications, including photovoltaics, solid-state lighting emitting diodes (LEDs), other applications. However, the toxic nature of lead-based MHPs, lanthanide-based MHPs emerged as an alternative, leading new opportunities for emerging such in near-infrared (NIR) imaging, NIR cameras, white LEDs, information encryption. Moreover, lanthanide doping significantly enhances stability optical MHPs. In this review, we attempted overview state-of-the-art synthesis strategies investigate structural, Furthermore, several applications solar cells, temperature sensors are discussed along with outlooks future directions.

Near-infrared phosphor-converted light-emitting diodes (NIR pc-LEDs) as a new NIR light source has outstanding application potential in the fields of spectroscopy analysis, sensing, imaging, and pattern recognition. Therefore, development phosphors with good luminescence thermal stability attracted much attention. To this end, we developed LiAlO2:Cr3+ garnet-type by high-temperature solid-state reaction method. Under 405 nm excitation, Cr3+ ions located tetrahedrons LiAlO2 emit emission broadband that covers 650-900 mixed several sharp narrowband R-line emissions, which showed excellent integrated intensity measured at 573 K is ∼90.86% 303 caused structural rigidity low expansion coefficient matrix material. An pc-LED device assembled optimized commercially available purple LED chip emitted output power ∼98.172 mW driving current 300 mA demonstrated an electro-optical conversion efficiency ∼9.09%, while it night vision monitoring biomedical imaging.

Near-infrared (NIR) light allows fast and nondestructive detection with deep penetration into biological tissues is widely used in food inspection, biomedical imaging, night vision security, other fields. Cr3+-doped NIR first region (NIR-I) phosphors have many interesting features that attracted a lot of attention recently. However, practical issues, such as low photoluminescence quantum efficiency poor thermal stability, need to be addressed. We synthesized Lu2SrAl4SiO12 garnet-type using high-temperature solid-state reaction method. Under blue-light (@ 430 nm) excitation, the exhibited broadband NIR-I emission range 600–1000 nm, an peak at 710 nm. This system unique, had multipeak sharp-line superposition Cr3+ ions were situated relatively strong crystal field environment, opposed weak environment for matrix. The optimal doping content was 2 mol %, its internal ∼76.8%. Surprisingly, this phosphor showed antithermal quenching effect, integrated luminescence intensity measured 573 K 206.3% 303 K. found caused by extremely expansion coefficient rigid structure matrix temperature range, well weakening electron–phonon coupling increasing temperature. optimized packaged blue chip phosphor-converted light-emitting diode device. source device output power 119.02 mW electro-optical conversion 11.02% under driving current 300 mA. application potential demonstrated high-resolution imaging.
