The Nobel Prize in Physics of 2023 was jointly awarded to Ekimov, Brus and Bawendi for the discovery and synthesis of quantum dots. In this context, discuss the applications of quantum dots.

(Quantum dots) refer to the semiconductor particles that are 2-10 nm in size and display photoluminescence.

These size dependent property of the quantum dots are responsible for their varied application.

Application of quantum dots:

i) Photoluminescence and tunable emitting property utilised in electronic appliances and their display.

(e) Quantum LEDs TVs.

ii) Healthcare—so reliable marker for detection of disease and drug delivery.

iii) Energy sector—Quantum dots can be utilized on solar panels for improving their efficiency.

iv) Sensors and signalling—small sensors based on quantum dots to detect and emit signals.

v) Low power consumption and improving efficiency of appliances.

(e) Replacing LEDs with Quantum Dots based display.
