How can I make codoped Y2O3:Eu3+/Er3+ nanoparticles from Y(NO)3.6H2O; Er(NO)3.5h20; Eu(NO)3.5h2O and urea?

Hello researchers Is this a random laser or just fluorescence?

I am using Rhodamine6G as gain medium and silver nanoparticles as scatterers on a microscope slide and laser input 532 nm comes from above.

Dear Lesley,

Instead of using Urea you may use Oxalic Acid as a precipitating agent to convert Rare Earth Nitrates into Oxalic acid and then convert this RE Oxalates into Y2O3:Eu3+,Er3+ after annealing at 900 Degree Celsius for 2-3 Hours.

Mr Rupesh Talewar

Thank you very much. Would you happen to know where I can find the procedure to carry out what you have advised?

Thank you.

We have used similar type of procedure to prepare Y2MoO6:Nd3+/Yb3+. Please go through the following link for synthesis procedure.
