Size-selective photoluminescenceexcitation spectra reveal that energy difference between the lowest optical translations increases due to stronger size quantum effect.
尺寸选择激发光谱表现了较强量子尺寸效应引起的最低光学跃迁之间能量差的增大。
2
Photoluminescence that persists for an extremely short time after excitation.
受激后持续时间很短的光致发光。
3
The excitation, photoluminescence and afterglow spectra as well as the curve of afterglow decay were investigated.
