Upconversion nanoparticles are nanomaterials that can convert near-infrared low-energy radiation into visible high-energy radiation through a nonlinear optical process. Up-conversion nanoparticles have the advantages of narrow emission spectrum, long life, good luminescence stability, not easily affected by the environment, low biological toxicity and high chemical stability. Alfa Chemistry offers a wide range of up-conversion nanomaterials. The alternative upconversion nanoparticles include oil and water dispersible particles. These photoluminescent nanoparticles are widely used in the fields of bioluminescence marking and imaging, lasers, solar cells and anti-counterfeiting technology. We can provide the best upconversion nanoparticles for your research.
