We report on synthesis of fluorescent nanoclusters consisting of palladium (Pd) atoms. We succeeded in synthesizing fluorescent palladium nanoclusters using poly-amidoamine (PAMAM) dendrimers as a template molecules. We found that the peak fluorescent wavelength was dependent on the molar ratio between PAMAM and palladium ion and trisodium citrate (reducing agent).
