Material and ingenious synthesis strategy for short-wavelength infrared light-emitting device
Abstract
Infrared (IR) light-emitting materials have wide applications. However, variety and economical accesses to obtain IR materials and devices are still limited, because the IR-emitting materials are always suffering from two obstacles, namely, lower absorption and lower emission efficiency. In this work, using a modified high-temperature solid-state reaction an efficient short-wavelength IR luminescent material is successfully synthesized. On the basis of the excellent luminescent properties, a convenient IR light-emitting diode (LED) device is fabricated by combining the novel IR material with a commercial UV LED chip. Besides the anticipation that it may lead to a boost of the application of IR device in different fields, importantly, we also consider that the ingenious synthesis strategy may open a door for obtaining novel ions doped functional materials.
