Features
The main objective of our research is to acquire profound understanding of "synthesis-structure-properties" relationship for the modern inorganic materials and to apply this knowledge for development of new materials with improved performance. The special attention is paid to the design of phosphors for white LEDs and photocatalysts with visible light response within oxide, oxynitride, oxynitride, and sulfide systems. The utilization of "green" solution processing towards these photoceramic materials is the paradigm of our group.

Targeted Application(s)/Industry
Through the synthesis of novel compounds in oxide, oxynitride, sulfide systems, development of new high-performance inorganic phosphors with various excitation and emission properties is possible. These high-performance phosphors are expected to be applied for the industrial use such as white light emitting diodes (white LEDs) and tools for sensing temperature.
