Quantum dots have found unusual use in agriculture
Many people are familiar with quantum dots primarily from QLED TVs from Samsung and other companies. However, this technology is also used outside of this area. An American company used nanoparticles that improve the image quality of televisions in agriculture, increasing the yield of plants with their help.
Vegetables and fruits absorb a certain amount of light. In addition, different plants "prefer" different shades of light more. After studying this issue, the American agricultural company UbiQD used quantum dot technology on its plantations. Representatives of UbiQD claim that the correct setting of quantum dots can make plants grow faster. As it turned out, some Dutch producers have long grown tomatoes in purple light, roses - in bright white, and peppers - in rich yellow. Thus, the selection of the desired glow gives the highest results.
Currently, UbiQD produces long sheets of foil from quantum dots, which are installed under the glass of the greenhouse. They generate orange light at a wavelength of about 600 nanometers. Before starting to commercialize the project, experiments were conducted that gave positive results. So, in New Mexico (USA) cucumbers and tomatoes were grown under the foil; in the Netherlands - strawberries and tomatoes; in Canada — cucumbers and tomatoes.
Currently, UbiQD has received several grants from NASA to develop a foil to protect against UV rays in space and is also trying to expand the geography of its products to other countries and regions. The company notes that agriculture is an important customer for quantum dot manufacturers. Every year, they use more than a billion square meters of a foil based on these nanoparticles.
