The technology of applying quantum dots on film (or its manufacturing from them) turned out to be applicable not only to the production of TV screens, monitors and displays. As we have already understood, quantum dots absorb and emit light, which is necessary for plants to grow. For an efficient process of photosynthesis, plants need light of a certain wavelength, so the energy of the remaining simply remains unclaimed, or insufficiently effective. Quantum dots absorb light unnecessary for plants and give it back in the right range, thereby accelerating the growth of greenery to 50%.
Before the attempts to apply quantum dots in this industry, many methods have already been tried for the production of a film for greenhouses. But, as it turned out, they all had significant shortcomings.
- when using phosphors deposited on pvc, they exfoliate, lose their properties and, moreover, at the same time, gaseous hydrochloric acid was released.
- production of a film from a copolymer of styrene takes too much time and requires a lot of additional elements, while not demonstrating sufficient efficiency for such labor inputs
- the production of a coating from a fluorescent pigment based on melamine-formaldehyde resins is a very taxing process. And low photostability of rhodamines.
The agro-industry needs an non-toxic, eco-friendly, efficient way of processing solar energy for natural and rapid plant growth.
