Nanomaterial characterization - Coggle Diagram
Nanomaterial characterization
Composition
Apply a stimulus
Choose the right equipment
Property is associated to stimulus
Energy that interacts with material
Light
Microscopy and spectroscopy
Electrons
Probe
Physical
Light
UV-Vis
Light passes throught a liquid medium
Absorbance is detected
Absorbance is inverse of transmitance
Used to confirm the synthesis
Used to confirm the performance
Used to follow layer by layer filmes
Can act as a catalyst
Production of layer by layer film
Can check the dispersion of materials
Dynamic Light Scattering
Associate with Tyndal Effect
Gives size information
Particles scatter light in all direction
Particle must be small
Smaller particles move faster
The size of the particle is associated to the light wave
The curve shows the diameter of the particle
Gives stability, size distribution
Doesn't give shape
Electron to material interaction
SEM
TEM
Shows shape and morphology
Probe to material interaction
AFM
Thickness
Similar to a record player
Ellipsometry
Shows thickness
light interaction
layer films
Sample is fixed
Refractive effect explains thickness
Use material with refractive index
The refractive index of light changes, it's transformed into thickness
Used to verify the quantity of material deposited
