We work in Dyes solution,we need to enhanced optical properties by make laser ablation of Ag in this dyes solution.
Yes it is possible, but the high laser fluence necessary for ablation probably induces a partial rhodamine degradation. I think it is of fundamental importance the frequency of the laser line, you should make sure not to work with frequencies that are absorbed by the dye molecule.
Yes you can but i suggest to do that in two directions the first one produce the Ag particles in this solution directly, the second to produce the Ag particles in alternative liguid like distil water and then mixed with your solution .Make comparison between these two solutions and check the structure variations.Also you can study the effect of different pulses, laser energy , and spot size on the final solution and the specifications of Ag particles.
Dear Dr. Galeb
Yes you can , but be careful the notes of Dr. Lusi and Dr. Nizar its very important ,My PhD student is working to preparation dye random laser ( NPS +Dye + polymer )if you like we can discusses the set-up and results .
Regard
Dear Dr. NIZAR JAWAD HADI,
Dear Dr. Michael Kompitsas,
Dear Dr. Luisa D'urso,
Dear Dr. Sara Kareem,
Dear Dr. Jassim Mohammed Jassim,
Thank you so much, our goal to improve , enhance & develop active laser medium by using nanoparticles in this dye .We use nano collide that prepared by laser ablation which have a very large surface area. By controlling some parameters we can chose band of laser.
Best Regards
Ghaleb
