We investigate the electronic structures and magnetic properties of ZnO doped with N,Cu,and (Cu+N) by using a first principles method and considering the strong
A new type ofgermanate-tellurite glass with doped Tm3+ ions is synthesized and its 1.8 μm emission properties have been studied for its application as a laser
In literature,some experiments of the interaction of a singly ionized ion with clean metallic surfaces were related to electron and visible light emission.[1-4]
Enhanced multiwave mixing processes due to atomic coherence have been experimentally reported in several multilevel atomic systems.[1-3] The keys in such enhanc
Broadband waveguiding through light-emitting strips directly written in a blank lithium fluoride crystal with a femtosecond laser is reported.Light guiding was
