What kind of UV box I should use to view ZnO samples (powders and alcoholic solutions)?

05 May 2016 1 6K Report

I have synthesized some ZnO nanoparticle samples. I am dissolving them in MeOH/ DMSO etc. I want to see the luminescence as shown in various papers.

e.g. Chem. Commun., 2011, 47, 11921–11923, J. Mater. Chem., 2012, 22, 8221, NewJ.Chem., 2015, 39, 2881, Chem. Mater. 2010, 22, 3383–3388 et.

I am using the UV exposure box that the organic chemists use. But it is of no use.

Please suggest me what kind of UV box I need.

thanks

Thanks a lot for your answer. So far I have been able to view the fluorescence of my samples using a hand held lamp of 312 nm and also another lamp of 365 nm.

However, at 254 nm, the samples are do NOT fluoresce as much.

Some time ago, I saw a UV box (black in colour from inside) which was used to view the fluorescence from some samples.

However, none of the commonly available UV light tubes (for disinfectant etc.) were able to excite my samples.

Although I am now able to view my samples under UV light using the lamp but it is NOT a convenient way especially for recording the photographs.

I would be glad if you could suggest me some appropriate method/ device.

Thanks in advance.
