Furthermore, photoluminescence (PL) spectroscopic analysis shows a strong near band edge emission.

同时，光致发光(PL)光谱的分析显示出强的近带边发射峰。

The band edge emission was observed in the PL spectra at room temperature. Its intensity was related to quality of the crystal.

在室温下的PL测量中见到了带边发射，其强度与晶体质量有关。

Blue shift appears both on the absorb edges in the absorption spectra and on the band-edge emission in the luminescence spectrum.

在紫外吸收谱中表现为吸收边明显蓝移，而在光致发光谱中，表现为带边发射的蓝移。

Its cutting-edge technology ensures that the B-Class Electric Drive is not only sustainable (because it offers local emission-free driving) and agile (because of its high torque and acceleration), but also fully networked.
