Electrospinning preparation of ErFe_0.95Co_0.05O₃ nanofibers for dual-band laser absorption

The advancement of laser detection technology has rendered single-band laser suppression materials insufficient for reducing the risk of target exposure, highlighting the urgent need for research on dual-band laser suppression materials. Currently, laser detection primarily involves the 1064 nm or 1540 nm laser bands, necessitating the achievement of low spectral reflectance at these two wavelengths. ErFe_0.95Co_0.05O₃ nanofibers were prepared using the electrospinning method. Utilizing the energy level transition mechanism of Er³⁺ ions and the nanofibers’ complex three-dimensional network, low reflectances of 22.28% at 1064 nm and 33.72% at 1540 nm were achieved. The micro-morphology and spectral reflectance of ErFe_0.95Co_0.05O₃ nanofibers can be optimized for laser suppression performance by adjusting heat treatment processes like calcination temperature. Therefore, the research presented in this paper will contribute to the development of novel multi-band compatible laser suppression materials.
