Hello. I'm actually was an applied physic student with some basic in Chemistry. So, first of all, I admit i made a mistake in believing Europium nitrate can be dissolved in chloroform. So currently I'm looking for a solvent that can dissolves all three materials together. Please advise me in this matter. Unfortunately, i have already received the material and unable to change the materials.
PVK is poly(N-vinylcarbazole), PBD is 2-(4-biphenylyl)-5-phenyl-1,3,4-oxadiazole and europium nitrate is Eu(NO3)3.5H2O .
