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 testing result of photoluminescence spectra at room temperature shows that all the samples have two emission bands, that is, UV emission band near the band-edge and visible emission band.
室温下样品光致发光光谱的测量结果表明：所有的样品均有两个发射带，即近带边紫外发射和可见发射带。
