Research Topics

01

Growth of Halide Single Crystals

Halide perovskite single crystals are grown mainly by the Bridgman–Stockbarger method and by vapor-phase transport.

02

Optical Characterization

Luminescence and optical absorption are evaluated by photoluminescence, transmittance, and infrared absorption measurements.

03

Radiation-Detection Properties

Scintillation responses to neutrons and gamma rays are characterized with a view to applications in radiation detectors.

04

First-Principles Analysis of Inorganic Materials

Electronic-structure calculations using Quantum ESPRESSO and VASP are employed to clarify luminescence mechanisms and the origins of material properties.

05

Electronic-Structure Database

An electronic-structure database of inorganic materials is being constructed on the basis of first-principles calculations.

06

Analysis Software Development

Software for optical characterization and other research-support tools are developed in Python.

Facilities and Instruments

Photoluminescence (PL) spectroscopy
Optical transmittance measurement
Fourier-transform infrared (FT-IR) spectroscopy
