Fabrication and Properties of Nano-photonic Glasses Controlled by High Temperature Deformation Process

制备了低软化透明磷酸锡（SP）玻璃，并对其玻璃化转变温度、折射率和粘度等基本物理性能进行了评价。研究了热压印条件对制备SP玻璃微方格图案的影响。通过对温度、压印压力和保持时间三个工艺参数的优化，得到了具有良好再现性的SG图形。通过改变入射光的入射角，将白色光选择性地反射到SP玻璃上的部分亚微米点图案上。

Low-softening transparent tin phosphate (SP) glasses were prepared and their basic physical properties such as glass transition temperature, refractive index, and viscosity were evaluated. Effect of thermal imprinting conditions on fabricated micro square grid (SG) patterns was studied for SP glasses. Fabrication conditions were optimized by the three processing parameters of temperature, imprinting pressure, and holding time for the SG patterns with good reproducibility. The white light was reflected selectively for different wavelengths by changing the incident angle of light into the part of sub-micro dot patterns thermally-imprinted on the SP glass.
