Abstract

A new material, LiInS2 (β-NaFeO2 type: wurtzitelike structure), for blue-light emission is proposed. A deep blue-band emission is observed by photoluminescence measurements at 77 K. The peak value is 453 nm for colorless as-grown crystals. From the annealing studies in a sulfur atmosphere, sulfur vacancies are responsible for the blue-band emission.
