Perovskite Quantum Dots Lasers Services


Perovskite Quantum Dots Lasers Services

The perovskite quantum dot laser is a coherent light source with strong luminous intensity and perfect directivity, which consists of a pump source, a double mirror cavity and a perovskite quantum dot gain medium. Compared with traditional metal-chalcogenide nanocrystal, perovskite quantum dot has obvious advantages, such as quantum confinement effect, large absorption cross section, wavelength harmonization defect tolerance, etc., and it is a competitive candidate material for optical gain medium. The development of non-toxic and lead-free halide perovskite and the improvement of the stability of perovskite quantum dots will further improve the commercial application performance of perovskite quantum dot lasers. Alfa Chemistry has experienced researchers in quantum dot research, relying on advanced instruments and techniques, and can bring significant optimization services for Perovskite quantum dot lasers.

Services for perovskite quantum dot lasers

Technologies for product optimization

  • Stability Enhancement
  • Encapsulation is a method of reducing structural dissociation to avoid atmospheric environmental effects.

    Combining quantum dots with metal structures can reduce the auger process and increase the fluorescence lifetime.

    Larger quantum dots can be used to achieve optical gains.

  • Nontoxicity
  • Several non-toxic candidate elements of halogenated perovskite were replaced by lead :(1) tin; (2) germanium; (3) bismuth; (4) the indium; Antimony (5); (6) copper; (7) Double perovskite.

To expand the application of perovskite quantum dots in optical devices, Alfa Chemistry is constantly looking for innovative ways to meet your needs in areas such as improved material performance and energy science.
