Structural, linear and enhanced third-order nonlinear optical properties of Bi12SiO20 nanocrystals

- The BSO nanocrystalline powder, forming in cubic sillenite phase, was synthesized by a simple low-cost chemical method.
- The value of β for BSO nanocrystals was found to be four orders of magnitude higher for 6 ns excitation and two orders of magnitude higher for 30 ps excitation when compared to the single crystal data.
- In addition to the nonlinear absorption, we observed nonlinear scattering (NLS), making it an attractive candidate for nonlinear optical device applications like optical limiters.
