As soon as lanthanum takes that electron, this level rises ever so slightly, and then we jump down here and fill in the lanthanide.

一旦镧得到了电子，这一层就会稍稍上升，然后我们向下填一下镧系元素。

And instead of having the electron giving off energy as a photon, instead now the electron is going to take in energy from light and move up to that higher level.

与电子以光子形式施放能量不同,我们现在要从光中,获得能量到一个更高的能级。

Specifically, we have to take in this exact amount of energy in order to bump the electron up to higher energy level.

特别的，我们严格需要,这么多,来把电子，提升到更高的能级。

When the electrons cross the junction, they drop from the higher energy level to the lower one, and the energy each electron loses when it drops takes the form of light to a large extent.

FORBES: LED Light Bulbs Mature At Last

These pairs are difficult to break up, so any intruding electron, unable to displace an incumbent from a pair, must occupy a higher, vacant energy level within the superconductor in order to stay put.
