Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Nanomaterials are classed by how many dimensions lie in the nanoscale (1 to 100 nm).
Step 2: Detailed Explanation
Thin films have one dimension (thickness) in the nanoscale.
Fibres and nanotubes have two dimensions (diameter) in the nanoscale and a long length.
Quantum dots have all three dimensions in the nanoscale, so they are zero-dimensional nanomaterials.
Final Answer:
Quantum dots have all three dimensions below 100 nm, option (C). \[ \boxed{\text{Quantum dots (C)}} \]
