Preparation and Characterization of Self-Assembled Thin Film of MPS-Capped ZnS Quantum Dots for Optical Applications

Table 1

Calculated value of particle size (2𝑅_ave) by using the first exciton peak. First exciton peak (𝐸_1s1s) values are extracted from the second derivative of the absorbance spectra.
