Local and controllable growth of nanocrystalline silicon (nano‐Si) in a commercial borosilicate glass is demonstrated. The nano‐Si was formed in the subsurface region of the glass via aluminothermic reaction in the course of the irradiation of a 2D array of aluminum nanodisks fabricated on the glass surface with CW low‐power 633 and 532 nm lasers. The thermoplasmonic nature of the nanodisks heating is demonstrated: at low incident intensity, the phenomenon takes place only if the plasmon resonance of the array and the laser wavelength is close enough. However, when the laser beam intensity at the sample surface exceeds 8 MW/cm² mutual position of the plasmon resonance and the laser wavelength weakly influences the phenomenon. The nano‐Si formation is studied with Raman scattering technique, and the average size of the silicon nanocrystals is evaluated.

CW激光引发的玻璃金属纳米结构中纳米Si晶体的形成

演示了商用硼硅酸盐玻璃中纳米晶硅（nano-Si）的局部和可控生长。纳米硅是通过铝热反应在玻璃的次表面区域形成的，该过程是用连续波低功率633和532 nm激光器在玻璃表面上制造的铝纳米圆盘二维阵列进行辐射的过程中形成的。证明了纳米盘加热的热等离子体性质：在低入射强度下，仅当阵列的等离子体共振和激光波长足够接近时才会发生该现象。然而，当样品表面的激光束强度超过8 MW / cm ^2时等离子体共振的相互位置和激光波长对这种现象的影响很小。用拉曼散射技术研究了纳米硅的形成，并评估了硅纳米晶体的平均尺寸。
