Abstract

Bulk oxyfluoride glasses doped with Ag nanoclusters have been prepared using the melt quenching technique. When pumped in the absorption band of Ag nanoclusters between 300 to 500 nm, these glasses emit a very broad luminescence band covering all the visible range with a weak tail extending into the near infrared. The maximum of the luminescence band and its color shifts to the blue with a shortening of the excitation wavelength and an increasing ratio of oxide to fluoride components, resulting in white color luminescence at a particular ratio of oxide to fluoride; with a quantum yield above 20%.

The simplified energy configuration diagram illustrates the excitation and emission transitions in Ag nanoclusters by straight lines. The wavy red curve corresponds to relaxation in the excited state between the sub-levels of a single nanocluster, and energy transfer between separated nanoclusters, whose energy splitting depends on the parameters of the crystalline field around Ag nanoclusters sites, as e.g. in [15].
