Herein; we present a green synthesis method for magic sized nanoclusters (MSNCs) of CdSe. The formation of MSNCs was examined using various edible oils viz; olive oil; mustard oil; castor oil; coconut oil and cod liver oil as capping agents. The source of Selenium is cyclo-octeno-1;2;3-selenadiazole which was decomposed (typically at 150 °C) in high boiling solvent. The comparative study has been carried out to verify the effect of different edible oils as capping agents on formation of CdSe to form MSNCs. We observed that only a certain capping agent (oil) delivers MSNCs of CdSe with stable white light emission for more than 12 months. The so-generated CdSe MSNCs show bright white light emission when excited with 365 nm light. Finally; the long term stability of as-prepared MSNCs using certain oil as capping agent is reported.
