Deep Red Emitting Phosphors for Indoor Plant Cultivation

CSIR-NIIST developed a highly efficient blue light excitable deep red-emitting phosphors by utilizing a scalable route perfect for indoor plant cultivations since its emission and excitation spectra match well with the absorption of important plant pigments such as various phytochromes and chlorophylls, which are mainly responsible for plant growth.

CSIR-NIIST has developed a highly efficient deep red-emitting phosphor material, excitable by blue light, tailored for indoor plant cultivation. This innovative technology aligns with the absorption spectra of key plant pigments such as phytochromes and chlorophylls, essential for promoting plant growth. Its scalable production method ensures feasibility for widespread use in indoor farming systems, such as LED-based horticultural lighting, enhancing crop yield and quality in controlled environments.

• The phosphor showed higher blue absorption. Under the blue light, it shows high red emission efficiency.

• Hence this phosphor is perfect for making blue LED-based deep red emitting lighting systems, which are very cost-effective due to the utilization of blue LEDs rather than UV LEDs.

• The phosphor does not use any rare earth materials and is synthesized via a scalable route. Hence the product has a lower cost compared to the commercialized red samples.
