稀土离子和半导体纳米晶(或量子点)本身都是很好的发光材料,二者的有效结合能否生出新型高效发光或激光器件一直是国内外学者关注的科学问题。与绝缘体纳米晶相比,半导体纳米晶的激子玻尔半径要大得多,因此量子限域效应对掺杂半导体纳米晶发光性能的影响变得很显著,从而有可能通过尺寸调
Both rare earth ions and semiconductor nanocrystals (or quantum dots) are good luminescent materials themselves. Whether the combination of the two can produce new and efficient luminescence or laser devices has always been a scientific issue that scholars at home and abroad pay attention to. Compared with the insulator nanocrystals, the semiconductor nanocrystal has a much larger exciton Bohr radius, so the effect of the quantum confinement effect on the luminescent properties of the doped semiconductor nanocrystals becomes significant, making it possible to measure
