ABSTRACT We demonstrated uniform LC alignment on IB-irradiated aluminium tin oxide (AlSnO) by controlling the annealing temperature. Physico-chemical analyses were carried out to determine the surface modification and uniform LC alignment mechanism as a function of the annealing temperature. IB irradiation induced the breakdown of the chemical bonds of AlSnO, preserving its anisotropic characteristics along the direction of IB irradiation, allowing for uniform alignment of the LC molecules on the reformed surface. However, at annealing temperatures under the boiling point of the solvent, residual solvent remained on the surface, thereby prohibiting uniform LC alignment. Moreover, we obtained good optical transmittance in the visual region and good electro-optical performance. Therefore, the IB-irradiated AlSnO film annealed above 200°C exhibited good potential as an alternative candidate for LC display applications. Graphical abstract

溶胶-凝胶法制备Al掺杂SnO液晶器件的电光性能

摘要 我们通过控制退火温度在 IB 辐照的铝锡氧化物 (AlSnO) 上证明了均匀的 LC 排列。进行物理化学分析以确定作为退火温度函数的表面改性和均匀 LC 对准机制。IB 辐照诱导 AlSnO 的化学键断裂，沿 IB 辐照方向保持其各向异性特性，使 LC 分子在重整表面上均匀排列。然而，在低于溶剂沸点的退火温度下，残留溶剂残留在表面，从而阻碍了均匀的 LC 排列。此外，我们在视觉区域获得了良好的光学透射率和良好的电光性能。所以，在 200°C 以上退火的 IB 辐照 AlSnO 薄膜显示出作为 LC 显示应用的替代候选者的良好潜力。图形概要
