【资源】这篇Nature应该又够大家做一阵子的un-blinking量子点
|
||
|
量子点的blinking一直为人们所苦恼，人们试图寻找un-blinking的量子点，去年JACS有人做出来过，当时，Nature进行了highlight。今天，Nature发表了有关un blinking量子的文章，合成的方法我感觉不能算新，材料也大家熟悉的CdZnSe/CdSe Core/shel.不过他声称使用了三层的结构，发光强度大幅提高，blinking也消除了。大家信不信可以自己动手做做，我是没那条件啊，不然我就去做了，呵呵。 Non-blinking semiconductor nanocrystals p686 The usefulness of semiconductor nanocrystals is severely limited by the fact that they 'blink': they turn on and off intermittently under continuous excitation. Here, ternary core/shell CdZnSe/ZnSe nanocrystals are realized, in which the transition between CdZnSe and ZnSe seems to be radially graded rather than abrupt, and which show completely non-blinking behaviour and strong photoluminescence. http://www.nature.com/nature/jou ... ll/nature08072.html 看的出来，Nature还是给于了较高的评价。 大家到这里下载去吧。 http://www.namipan.com/d/04d2dcc ... ecc57c17208a7540700 http://www.namipan.com/d/ac1b4d8 ... dd7974a510107e51100 不好意思，不小心设成资源帖了。要是有人发过了，版主就删了吧，多不好意思，呵呵 [ Last edited by dawnlight on 2009-6-4 at 11:03 ] |
