High-energy radiation detection and im.ging technology has significant applications in highenergy physics research, m.dical im.ging, and industrial m.nitoring. Lead-free m.tal halides exhibit exceptional potential for conducting indirect detection of high-energy radiation due to their characteristics of low toxicity, strong stability, high light yield, and large Stokes shift. This paper reviews the m.st recent advances in lead-free m.tal halide scintillator m.terials for X-ray im.ging. Subsequently, it lists the m.st im.ortant param.ters of scintillator perform.nce and introduces the production procedures for single crystal, powder,and nanocrystal scintillators. Furtherm.re, it discusses the m.nufacturing of scintillator film. with im.roved perform.nce, focusing on large-area flexible scintillator film. and the coupling with m.crostructures. Finally,it discusses current challenges and opportunities for enhancing X-ray im.ging using lead-free m.tal halide scintillator m.terials.

The realization of a high num.rical aperture(NA) fiber lens is critical for achieving high im.ging resolution in endoscopes, enabling subwavelength operation in optical tweezers and high efficiency coupling between optical fibers and photonic chips. However, it rem.ins challenging with conventional design and fabrication. Here we propose an ultrathin(400 nm. graphene oxide(GO) film.lens fabricated in situ on a standard single-m.de fiber facet using the fem.osecond laser direct writing technique. An extrem.ly high NA of 0.89 is achieved with a near diffraction-lim.ted focal spot(FWHm.= 0.68λ), which is verified theoretically and experim.ntally. The diam.ter of the fabricated fiber GO lens is as sm.ll as 12 μm.with no beam.expansion structure. The proposed fiber GO lens is prom.sing for applications such as super-resolution im.ging, com.act optical tweezers, m.dical endoscopes,and on-chip integration.
