Abstract The B 2 O 3-Bi 2 O 3-AlF 3 glass system doped with Eu 3+, Tb 3+, Tm 3+ and triply
doped with Eu 3+/Tm 3+/Tb 3+ ions in different molar ratios were successfully synthesized …

Rare earth ion (Tb3+ and Eu3+)-doped alumina films were prepared by the aqueous sol-gel
method under various conditions. The influences of the OH groups (phonon relaxation) and …

Scintillators can convert high-energy rays into ultraviolet or visible light and are widely used
in medical diagnosis, safety inspection, and industrial flaw detection. Nowadays …

In silicate sol–gel glass doped with trivalent terbium, the intensity of violet and blue
fluorescence from the 5D3 level is highly dependent on terbium concentration, on the …

The 5D3 and 5D4 emission of Tb3+ under UV-excitation in the 4f75d band has been
measured as a function of the Tb content in Y–Si–Al–O–N glasses. A strong increase of the …

Rare-earth ions (Gd3+, Ho3+, Pr3+, Sm3+, Dy3+ and Tm3+)-doped alumina films were
prepared by the sol–gel method, using aqueous AlCl3-derived alumina sol. The ions were …

Silica-based sol–gel glasses activated by Er3+ ions are attractive materials for integrated
optics (IO) devices such as frequency upconverters and optical amplifiers. Monolithic erbium …

The inclusion of Tb 3+ ions doped into the storage phosphor BaFBr: Eu 2+ results in
increased purity of the host material as well as an improvement in the linearity of the …
