瑞典研究人员已公布了一项计划,准备制造能发射线性偏振光的量子点。林雪平大学的Anders Lundskog及其同事通过在基部已加长的微型六角形氮化镓金字塔的顶部“种植”量子点,使氮化铟镓量子点所发射的光处于受控状态。他们发现,发射光的偏振方向与基部延长轴是一致的。通过调节氮化铟镓中的铟含量,原则上就可将由量子点发射的光从紫外线波长调到红外线波长。这种方法的好 Swedish researchers have announced a plan to make quantum dots capable of emitting linearly polarized light. Anders Lundskog of Linköping University and colleagues controlled the light emitted by the indium gallium nitride quantum dots by “implanting” the quantum dots at the top of the elongated hexagonal gallium nitride pyramid at the base. They found that the direction of polarization of the emitted light is consistent with the extension of the base. By adjusting the indium content in indium gallium nitride it is in principle possible to redirect the light emitted by the quantum dots from the UV wavelength to the IR wavelength. This method is good
