General description

Yttrium oxide is an excellent mineralizing agent for spinel formation. It has a high melting point(2450oC), chemical stability, low coefficient of thermal expansion, high transparency for both visible (70%) and infrared (60%) light, low cut off energy of photons.

Application

Yttrium oxide was used in the preparation of pervoskite type structure, YAlO3, containing chrome ions.1 The effect of yttrium oxide dopant on the phase formation and sintering characteristics was studied. It may be used in the manufacturing of neodymium Nd:YAG lasers and in components of MOS and LED transistors.

As with all types of fuel cells, a Solid Oxide Fuel Cell (SOFC) is capable of efficiently transforming chemical energy into electrical energy.

Spectral conversion for solar cells is an emerging concept in the field of photovoltaics, and it has the potential to increase significantly the efficiency of solar cells. Lanthanide ions are ideal candidates for spectral conversion, due to their high luminescence efficiencies and rich energy level structure that allows for great flexibility in the upconversion and downconversion of photons in a wide spectral region (NIR-VIS-UV).

Rechargeable solid-state batteries are becoming increasingly important due to wide-spread use in computers, portable electronics, and vehicular applications.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
