|摘要:||Following preparation of isolated nano-sized magnetite particles in a low-concentration dispersant solution, this study investigated the magnetic and optical properties. Magnetic measurements indicated that the magnetite nanoparticles exhibited perfect superparamagnetism above the blocking temperature. Optical measurements revealed that the magnetic films exhibited good transmittance in the visible region and excellent UVB absorption. It has potential for use in optical applications (UVB-cut), such as sunglasses, heat mirror film and others.|
