Abstract

Crystalline borate materials have large potential for the technological applications. Morphological, structural and optical properties of Nd³⁺/Yb³⁺ codoped Al₄B₂O₉ nanopowders prepared by the polymeric precursor method were investigated and they have large potential to be tested in solar energy concentrators and IR laser devices. Random Laser (RL) emission at ~1062 nm, self-second-harmonic generation at 531 nm and self-sum-frequency generation at 460 nm were investigated in Nd_xY_1.00-xAl₃(BO₃)₄ nanocrystalline powders, for 0.05 ≤ × ≤ 1.00. The RL excitation pulse energy and wavelength were dependent on the Nd³⁺ concentration. Non-linear effects were also exploited.
