Body · points and prose

Technical concepts

Diagram
- Nano/Quantum dots - Basically tiny semiconductors - Physical property depends on size - Larger - VIBGYOR - Redish - Smaller - VIBGYOR - Bluish

Applications

(1) Solar Energy Efficiency a) → Early a singular photon could excite a singular electron only. b) → now a singular photon would

excite a quantum dot → will excite multiple electrons.

Diagram
photon → Q/D → (e-, e-, e-) [Enhanced Efficiency] ↓ Critical for net zero (2070)

c) India's target 500GW by 2030

(2) Entertainment Industry

a) → Considered as successor to LED technology

b) → will significantly improve pixels resolution → significant visual Enrichment & deeper colors

(3) Healthcare Industry

3.1 Diagnosis → Q-dots can be sent as probe into investigating issues like cancer, tumors, etc

3.2 Exciting the Q-dots with laser → crystal clear diagnosis.

3.3 Easier drug delivery by attaching it with the probe.

(4) Can significantly reduce Industrial & mining disasters by providing better

(5) Space sector : Improved Audio-visual communication; boost to both upstream & downstream services

(6) Semiconductor manuf boost.

(7) Nuclear Irradiation
