Article Synopsis
- A new method for creating an efficient optical scatter trap using 100-nanometre crystalline octahedral Silicon nanoparticles (Si-NPs) is introduced.
- This technique shows a remarkable increase in Raman yield—up to 10^8 times higher than bulk Silicon—highlighting the nanoparticle's effectiveness in trapping light.
- The synthesis process requires only 50 °C, making it suitable for use on various substrates in optical and photovoltaic applications.
Empowering an indirect band-gap material like Si with optical functionalities, firstly light emission, represents a huge advancement constantly pursued in the realization of any integrated photonic device. We report the demonstration of giant photoluminescence (PL) emission by a newly synthesized material consisting of crystalline faceted Si grains (fg-Si), a hundred nanometer in size, assembled in a porous and columnar configuration, without any post processing. A laser beam with wavelength 632.
