In order to be able to test, in commercially realistic light-emitting diodes, nanoparticles that have shown blue electroluminescence in prototype devices need to be adapted. Currently, we have two classes of hybrid nanoparticles that start from a 50 nm silica bead, on which InN or Eu2+ doped GaN have been grown. This makes these nanoparticles incompatible with the 100 nm thick polymer layer in commercial devices. In addition, solvents from which these polymers can be spincoated are typically toluene and xylene, in which our nanoparticles are currently not compaticle.

为了能够在商业上可行的发光二极管中进行测试，需要对在原型设备中显示出蓝色电致发光的纳米颗粒进行调整。目前，我们有两类混合纳米粒子，它们以 50 nm 硅珠为基础，在其上生长 InN 或 Eu2+ 掺杂 GaN。这使得这些纳米粒子与商业设备中 100 nm 厚的聚合物层不兼容。此外，可以旋涂这些聚合物的溶剂通常是甲苯和二甲苯，我们的纳米颗粒目前在其中不相容。
