The World Population Prospects 2019: Highlights, published by the Population Division of the UN Department of Economic and Social Affairs, reports that the world population could reach its peak around the end of the current century, at a level of nearly 11 billion. This increase will need to be accompanied by increases in food production, and that too in a world where arable land is becoming an increasingly scarce resource. To address this problem, a relatively new agricultural practice known as Vertical Indoor Farming (VIF), which relies on height, rather than width, to generate agricultural production has emerged as a form of ‘sustainable cultivation of plants.’ It is important to mention that chlorophyll a and chlorophyll b absorb red light ranging from 600 nm to 700 nm wavelength. Red emission from AlGaInP red LED chip is comprised of rather narrow emission spectra from 625 nm–640 nm. In this review, we elucidate a series of transition metal (Cr3+/Mn4+)/ rare-earth (Eu2+) doped silicate and aluminate phosphors emitting in the red region (600 nm – 700 nm) exhibiting high luminescence efficiency for the fabrication of phosphor-converted red LED, which can be mounted on blue LED chip. Consequently the red LED, which will be fabricated by using these red emitting phosphors mounted on blue LED chip will provide the red light in 600 nm to 700 nm region, which can be absorbed by chlorophyll a and chlorophyll b. Solution synthesis mediated approaches will be discussed for the synthesis of these high efficiency phosphors.
