請教英文好的大俠三句英文句子的語法,看看小妹寫的是否正確

第1句:However, because the emission spectra of these phosphors absences in the red region, so YAG: Ce based white LED has a poor color rendering index (CRI). 網(wǎng)友修正:However, these phosphors lack the red region in their emission spectra of , therefore YAG: Ce based white LED has a poor color rendering index (CRI). 樓主疑問:是不是of 應(yīng)該移到lack 后面:However, these phosphors lack of the red region in their emission spectra , therefore YAG: Ce based white LED has a poor color rendering index (CRI). 第2句: It can be seen clearly that the enhancement of Ce3+ co-doped SrSiON:Eu2+ is about 140% compared with the one without Ce3+ co-doped. 應(yīng)該寫明具體是什么增加了,折中表達(dá)法很不合理 樓主疑問:改成這樣可以么:It can be seen clearly that the luminescent properties of SrSiON:Eu2+ ,Ce3+ phosphor are enhanced about 140% compared with the one without Ce3+ co-doped. 第3句:Therefore, the electric dipole-dipole interaction predominates in the ET mechanism is from Ce3+ to Eu2+ in SrSiON: Eu2+,Ce3+. 這句話很難看懂,句子結(jié)構(gòu)不合理 樓主疑問:改成這樣可以么,Hence, the energy transfer from Ce3+ to Eu2+ ions is predominantly attributed to the electric dipole-dipole interaction. |

你看看這樣OK不.... 第一句:However, YAG: Ce based white LEDs with low color-rendering index (CRI) because of the lack of red light component . 第二句:你還是沒有說明增強(qiáng)的140%是什么。發(fā)光性能不能說增強(qiáng)140%。你可以說是發(fā)射強(qiáng)度,或是什么,他得是一個值。比如說:It is obvious that emission intensity of the SrSiON:Eu2+phosphors are enhanced about 140% by co-doped with Ce3+. 第三句:The energy transfer from Ce3+to Eu2+in the host lattice of SrSiNO is quite common,and has been observed in aluminum oxynitride phosphor, which is generally attributed to the electric dipole-dipole interaction. |
