Optical studies showed that the absorption edge of SnO2:V的NP显示出与钒的浓度增加红移。This redshift leads to the decrease in the optical band gap from 3.25 eV to 2.55 eV. A quenching in luminescence intensity has been observed in SnO2:V的NP,相比于未掺杂的样品。罗丹明B染料(罗丹明B)已被用于研究的所有合成NP的光催化降解。相比于未掺杂的SnO2纳米粒子,SnO的光催化活性2:V的NP得到了提高。RhB dye was considerably degraded by 95% within 150 min over on the SnO2:V纳米颗粒。SN - 1687-8108 UR - https://doi.org/10.1155/2019/2157428 DO - 10.1155 /二百一十五万七千四百二十八分之二千○十九JF - Hindawi出版KW - - ER在凝聚态物理PB进展 -
