The Role of Solvent Environment on the Optical Behavior of Chemically Synthesized Silicon Nanoparticles

Table 2

Relation between solvent, etching no. of rounds, polarity index, and color of emission for Si NPs under UV excitation.

Sample	Number of rounds	Polarity Index	Picture of sample under UV lamp (comparing with pure solvent)
Ethyl acetate	4	4.4
1,2-Dichloroethane	4	3.5
Benzene	4	2.7
Toluene	4	2.4
Carbon tetrachloride	4	1.6
