Green Science Alliance developed quantum dot film

Environmental problems such as climate change, extinction of species, water shortage, plastic pollution, and deforestation are becoming disastrous problems nowadays. Not to mention food scarcity problem is becoming a critical issue due to human population explosion. Therefore, efficient agriculture to harvest more crops is very important for food scarcity problems.

Plants absorb CO2 and make oxygen and starch by the process called photosynthesis with the help of solar light irradiation. In fact, plants are utilizing not all of solar light and they prefer mainly blue and red light in the solar light for their photosynthesis and growth. Plants and plant leaves look green because they reflect green light since they do not use green wavelength color in the solar light. Recently, it is known that tomato likes magenta color, rose like whitish color and chili pepper prefer yellowish color for their growth.

Quantum dots are super tiny materials (0.5 - 9 nm) with optical properties that follow the rules of quantum chemistry and quantum mechanics. These quantum dots are also called "artificial molecules" because each quantum dot is composed of only several dozen to thousand number of molecules. At this size range, the energy levels of electrons are no longer continuous and are separated due to the physical phenomenon known as the quantum confinement effect.
