Herein, a novel transparent phenyl vinyl silicone resin nanocomposite containing exfoliated fluorescent Eu‐containing hydrotalcite‐like compound ( EFHSN ) is developed to serve as a dual role of color conversion and encapsulation material. Excited by near‐ NUV light, the EFHSN emits a strong characteristic red light (614 nm). Meanwhile, the EFHSN shows not only excellent transparency ( T > 95%) in the UV ‐Vis region and high refractive index (1.46) but also superior thermal stability, which could meet the need of commercial encapsulation materials and optical application. Therefore, the EFHSN is expected to be used in InGaN‐based NUV light‐emitting diodes and flexible optoelectronic device.
