Product Description

Insoluble perovskite quantum dots (QDs) are advanced semiconductor nanomaterials known for their outstanding optical properties. These quantum dots are engineered to provide stable and efficient light emission, making them highly suitable for various research and technological applications such as optoelectronics, sensing, and imaging. Due to their insoluble nature, they can be easily incorporated into solid matrices or films.

Structural Characteristics

The structure of insoluble perovskite QDs consists of CsPbX₃ (X = Cl, Br, I) nanocrystals as the core. In this configuration, the perovskite core serves as the primary light-emitting component. By adjusting the halide composition (Cl, Br, or I), the emission wavelength of the quantum dots can be precisely tuned across different regions of the visible spectrum, enabling flexible optical design for various applications.

To further enhance durability and environmental resistance, the surface of the CsPbX₃ nanocrystals is coated with a silica layer. This silica shell acts as a robust protective barrier that isolates the perovskite core from external factors. At the same time, the inorganic silica coating helps maintain the structural integrity of the nanocrystals and prevents aggregation, thereby improving the overall stability and reliability of the quantum dots in solid-state environments.

Key Characteristics

Insoluble perovskite QDs exhibit high luminescence efficiency, producing strong and bright fluorescence under excitation and making them well suited for applications that require reliable optical performance. They also feature a narrow full width at half maximum (FWHM), allowing the emission spectrum to remain sharp and well-defined, thereby providing excellent color purity and spectral precision. In addition, these quantum dots demonstrate high stability, largely due to the protective silica coating that helps shield the perovskite core from environmental factors such as moisture and oxygen. Finally, they are cadmium-free, making them a safer and more environmentally friendly alternative to traditional cadmium-based quantum dots.
