In light of global urbanization, the key to long-term agricultural development is a more efficient use of arable land, labor, and modern technology. Indoor plant factories are promising solutions for future horticulture production and food supply to densely populated urban areas. The light-emitting-diode (LED) is revolutionizing general illumination with the promise of enormous energy savings when widespread adoption occurs. However, current LED technologies for plant cultivation are less developed compared to LEDs for general lighting. LEDtech-GROW offers innovation in the field of LEDs that entirely satisfy the needs of plants and cannot be achieved with any LED technology currently available. To maximize such benefits, we will address a few critical issues: light quality, long-term stability, and the environmental impacts of the chosen solutions. We will develop inorganic phosphors that convert as much electrical energy as possible into a Photosynthetically Active Radiation (PAR) spectrum of plant photoreceptors, which differs from one required for general lighting. This groundbreaking technology will deliver double and triple-wavelength emitting phosphors that increase light output for cryptochrome and phytochrome photoreceptors while ensuring high color quality. The fundamental concept of inner-particle energy transfer between Bi3+ and Eu3+ ions significantly contributes to the development of plant-grow-targeted LEDs. Therefore, we will design and fabricate highly efficient, environment-friendly, and moisture-resistant plant-grow-targeted LEDs based on bismuth-sensitized Eu3+-activated single-component phosphors for the whole PAR spectrum.
