    Abstract

    Infrared (IR) thermal imaging has aroused great interest due to its wide application in medical, scientific, and military fields. Most reported approaches for regulating thermal radiation are aimed to realize IR camouflage and are not applicable to enhance thermal imaging. Here, we introduce a simple and effective method to process porous glass by femtosecond laser scanning, where distributed nanocavities and nanowires were produced, which caused improvement of the treated glass emissivity. The as-prepared sample possessed better IR thermal radiation performance but lower transmittance to visible light. We also demonstrated its applicability by placing it in different backgrounds, where the IR image temperature of laser-treated glass was closer to the actual environment, and this strategy may provide a new vision for enhanced thermal imaging.
