Abstract:
In this work, for the first time, uniform blue-emitting EuCl(2) nanoprisms and nanorods were synthesized from Eu(CCl(3)COO)(3)·2H(2)O [or Eu(CH(3)COO)(3)·H(2)O] by a novel mild liquid reduction route, using acetamidine hydrochloride (or picolinamidine hydrochloride) as the reductant in oleylamine. The synthetic reaction even can take place under an atmosphere in the absence of inert gas at around 300 °C. The EuCl(2) nanoprism dispersion in n-hexane showed an intense blue emission when excited by UV light.
