Nanocrystalline Ceramic Luminophores for Short-and Mid-Infrared
Original language description
A great scientific effort has been dedicated to increase the lasers power and to shift their operating wavelengths from traditional telecommunication range 1.2-1.7μm to longer wavelengths. The breakthroughs in many fields; such a LIDARs, chemical sensors, etc.; are associated with an existence of high-power lasers operating in the infrared range 2 - 5 μm. Although the results in the field of chalcogenide or fluoride glass have opened new horizons, the thermal and chemical stability of such class of materials significantly limit the overall transmitted power and their applicability. Transparent ceramics may face this challenge because of their high thermal and chemical stability, low phonon energy and high transparency in short- and mid-infrared. We present the nanocrystalline ceramic luminophore based on the compound (Ho0.05 Y0.95)2 Ti2O7 crystallizing in pyrochlore structure. The luminophore was constituted of the partially sintered ceramic nanoparticles of the size around 30 nm and its phonon energy was smaller than 700 cm-1. The luminophore revealing an emission around 2.0 μm and 2.9 μm. The further tailoring of the chemical structure can further contribute to the preparation of novel ceramic luminophores emitting in short- and mid- infrared as a high-thermally and chemically stable alternative to conventional glass fibers.
