1) Low-temperature photoluminescence
低温光致发光谱
2) photoluminescence spectroscopy (PL)
低温光致发光光谱
3) Photoluminescence (PL) spectra at room temperature
室温光致发光谱
4) temperature dependent PL measurement
变温光致发光谱
1.
from temperature dependent PL measurement spectra we determine the binding energy of the acceptors to be 131 meV at 81 K, suggests that it is a Sb_(Zn)-2V_(Zn) complex with activation energy of about160 meV.
XRD和拉曼谱表明Sb~(3+)代替Zn~(2+)进入ZnO的格位,随着浓度的增加纳米粒子半径变小;通过变温光致发光谱,计算出在81 K时受主束缚能为131 meV,认为形成了Sb_(Zn)-2V_(Zn)复合体,理论计算其受主束缚能为160 meV。
