EN Bi3TeBO9 crystal is an excellent nonlinear optical material as well as an efficient host matrix for luminescent rare earth ions.1,2 Investigated Bi3TeBO9 crystalline powders were synthesized by means of the modified Pechini method. The vibrational properties of Bi3TeBO9 were studied using µ-Raman spectroscopy.3 Moreover, Bi3TeBO9 powders doped with Nd3+ ions show the efficient near-infrared quantum cutting process by cooperative down-conversion of active Bi3+ and Nd3+ ions. As a result, the investigated systems efficiently concentrate the ultraviolet/visible radiation in the near-infrared spectral range and can be potentially used as effective spectral converters in new multi-functional miniaturized optical devices.
