One of the largest drawbacks of LEDs has to do with cool white LEDs, high color temperature LED light fixtures that emit a high level of blue light. The level of blue light emitted by these cool white LEDs is significantly higher than that emitted by most other outdoor LED sources. As ...
Crystal field splitting:The energy gap between the splitting of d-orbitals of the metal ion in presence of ligands is known as the crystal field splitting(Δ). The magnitude of(Δ)is depends on the nature of metal ions and the ligands. ...
aThe charge-doping could introduce a polaron level between the HOMO and LUMO levels, which results in a narrower frontier orbital energy gap, lower exitation energy, and smaller bond length alternation parameter comparing to the undoped system. 充电掺杂能介绍一个polaron水平在拉人之间和 LUMO水平,导...
