I'm excited seeing all 1 thru 6 accomplishments of Dr Kowlgi, most of which are game changers and may have US patent potential, but my personal favorite is having synthesised Silicon quantum dots. They are revolutionary.
Here's what one website says about SiQD:
"Silicon Advantages over Traditional QDs
Nanocrystalline silicon has great potential value because it is based on the same material that is the foundation of the electronics industry. Most QDs on the market today contain toxic metals (e.g., cadmium, lead, or indium) that severely limit their market reach. SiQDs are metal-free QDs that possess all of the favorable properties of their toxic metal-containing counterparts with the added benefits of elemental abundance, biologically compatibility, and optical properties that are tunable throughout the visible and near-IR spectral regions as well as in the temporal regime.
They do not contain any heavy metals (e.g. Cd, In, Pb).
Silicon is abundant and its chemical/electronic behavior is well-understood.
Are non-toxic and biocompatible with human tissue.
Bright photoluminescence (up to 85% quantum yield) and tunable from the visible to the near-IR.
Low self-absorption due to a large Stokes shift of >400 meV.
Stable photoluminescence in various composite materials at elevated temperatures of over 100 ᵒC and high humidity.
The size tunability of colloidal SiQDs make them an attractive alternative to fluorescent dyes or doped phosphors since many colors can be achieved from the same material. Compared with dyes, SiQDs are exceedingly more stable.
Simply put: SiQDs are changing how we use light and color."
