Spectroscopic study of Eu³⁺ ions in heavy metal fluoride and oxide glasses

Abstract

Two types of fluoride and oxide systems belonging to the heavy metal glass family have been studied. From absorption and emission spectra together with Judd -Ofelt analysis, spectroscopic parameters of Eu 3+ ions in both optical systems were evaluated and compared. The new oxide glassy system based on PbO -B 2 O 3 -Al 2 O 3 -WO 3 exhibits interesting spectroscopic properties of Eu 3+ ions for application as a redemitting optical material.

Magneto-optical investigations of rare earth doped sol–gel derived silicate xerogels

“…This is consistent with the Mössbauer spectroscopy data, which pointed out the absence of a threefold or fourfold axis of symmetry at the rare earth site [21]. The characteristic PL lifetime lies between the similar data reported in conventional silicate glasses and fluoride glasses of about 2.3 ms [22] and 6.26 ms [23], respectively.…”

Spectroscopic studies of Sm3+ and Eu3+ co-doped lithium borate glass

“…The standard procedure was employed in this case: the intensity of the 5 D 0 -7 F 1 magnetic dipole transition is host independent and its radiative transition probability for different hosts is reported to be between 30 and 60 s −1 [27][28][29][30][31][32][33][34][35][36][37]. Then it is possible to express the ratio of the radiative transition probabilities A R in terms of the ratio of areas S under corresponding emission curves [32,33]:…”
