网友回复:(怎么没人回答啊？网友回复怎么没人回答啊？ 金贝不够我可以增加啊网友回复怎么没人回答？网友回复有机溶剂一般也是会有荧光的，UMCM-1浸泡在有机溶剂中再测荧光的话，出来的荧光应该是两种物质的叠加，波峰的位置也就自然会出现“蓝移”或“红移”，不知道这样理解对不对？希望对你有所帮助！网友回复 引用内容:

没有共轭基团的有机溶剂不会有荧光吧。 事实上，所有物质都是有荧光的，只是有的荧光光强很弱，一般的无法检测到，所以就认为有些物质没有荧光。但是，两者混合起来，就不一定了。网友回复溶剂显色效应，很正常的，就是随着溶剂极性增加，D-A结构的物质在相同激发波长的情况，发射峰红移，强度降低。我看你还问了个荧光寿命的问题，这些都是基础的，你自己看下相关的书。网友回复 引用内容:
