Table 3 Particle size statistics and estimated bandgap of samples Bi-201 to Bi-206

From: Size-controllable synthesis and bandgap modulation of single-layered RF-sputtered bismuth nanoparticles

Number	$\bar{dμ}$ (nm)	$\bar{d}$ (nm)	$\bar{d_{v}}$ (nm)	E_g(eV)
Bi-201	12.9	13.0	13.2	2.63
Bi-202	17.5	18.5	18.9	2.50
Bi-203	21	20.7	21.7	0.85
Bi-204	28.7	28.9	29.9	0.91
Bi-205	14.5 and 45.1	38.3	42.3	1.39
Bi-206	15.3 and 52.6	41.1	45.9	0.45
Bi-101				0.18

The bandgap of sample Bi-101 (Bi thin film) is listed as a reference.
