Quantum dots (qds) are nanoscale crystals of semiconductor Material that exhibits excellent optoelectronic properies such as tuvable Wavelength, narrow emission spectrum, and high photoluminescence yields. First Discovered in the 1980s, these Materials Have Been the Focus of Intense Research Because of Their Potential to Providant Advantages in A Wide Variety of Optical Applications, Among Them Light-Emitting Diodes (LEDS). Quantum dots are expected to deliver low -cost, Higher Energy Efficiency and Greater Wavelength Control for A Wide Range of Products, Including Lamps, Displays and Photovoltaics.
Ever sincet the First Cadmium Selenide (CDSE) QD-Based Light-Emitting Devices (Qleds) We Reported in 1994, the dominant Materials for qleds Investigated Sence then have been limited to wurtzite or zinc blende cd-based qds. Similarly, The Best Developed and Studied Colloidal QD Lasers have been fabricated from CD-Based semiconductors.
Now, Researchers have presented a new family of Photoelectric Materials for Light-Emitting Devices: Colloidal All-Inorganic Perovskite Cesium Lead Halide QDS. This New Material Could Find Applications in LEDS and Lasers, and has an eSpecially Big Potential in High-Performance Displays, Lighting, Monochromatic Narrow-Band Photadetectors, and Optical Communications.
"We discovered that our newly engineed quantum dots possess superior optical gain properies, representing a new class of processed, low-threshold, truly stable and wavelength-tuunable matt. Nanjing University of Science and Technology. "The solution process Ability of these QDS ALSO MAKES APPLICABLE FOR DEVICE FABLE FROM SIMPLE AND Cost-Effective Printing and Spraying Technologies. »»
