Optimal carbamide concentration in the mixture for enhanced luminescence from an aqueous solution of rhodamine 6G

An investigation was made of the dynamics of the luminescence spectrum of aqueous solutions of rhodamine 6G with added carbamide. It was established that the maximum enhancement of the luminescence intensity of aqueous solutions of rhodamine 6G was only achieved with an optimum ratio of the numbers of rhodamine 6G and carbamide molecules in the solutions.
