Abstract
Contrary to most Pr3+-doped materials, Pr3+-doped BaGd2(MoO4)4 crystals do not generate the 1320 nm photoluminescence, which is used as an amplifier for O-band optical communications. However, it is found to generate a broad emission band in the wavelength region of 1400–1550 nm with full-width at half-maximum of 130 nm. Pr3+-doped BaGd2(MoO4)4 with broadband near-infrared emission is expected to be useful as an amplifier material in the E- and S-band optical communication systems. Disappearance of the 1320 nm emission in BaGd2(MoO4)4 is explained by the energy gap law with high maximum phonon energy (944 cm−1) of BaGd2(MoO4)4. The 1400–1550 nm emission has the maximum intensity at 1 mol. % Pr3+ concentration. The concentration quenching is understood by cross-relaxation process.
