Pb<sub>4</sub>O<sub>3</sub>I<sub>2</sub>: A Lead Oxyhalide IR Optical Crystal with an Unprecedented <sup>1</sup><sub>∞</sub>[O<sub>3</sub>Pb<sub>4</sub>] Chain Featuring a Wide Transmittance Range and Large Birefringence

Among the infrared (IR) optical material systems, the heavy-metal oxyhalide system has become an emerging system in recent years. Introducing heavy-metal cations and halogen anions with large atomic numbers is conducive to widening the IR transparency window and improving the birefringence value. Our experiments focus on the PbO-PbI<sub>2</sub> system and find a new lead oxyhalide, Pb<sub>4</sub>O<sub>3</sub>I<sub>2</sub>. The structure of Pb<sub>4</sub>O<sub>3</sub>I<sub>2</sub> is mainly composed of [OPb<sub>4</sub>] basic structure units, and triple-row [OPb<sub>4</sub>] units further connect to form unprecedented <sup>1</sup><sub>∞</sub>[O<sub>3</sub>Pb<sub>4</sub>] infinite chains. Pb<sub>4</sub>O<sub>3</sub>I<sub>2</sub> exhibits a wide IR transmission range from 0.49 to 15.0 μm, and theoretical calculation shows that Pb<sub>4</sub>O<sub>3</sub>I<sub>2</sub> has a large birefringence of Δ<i>n</i> = 0.098 @1064 nm. The results show that Pb<sub>4</sub>O<sub>3</sub>I<sub>2</sub> is an example of an IR optical material with good optical properties in heavy-metal oxyhalides, which significantly enriches the diversity of oxyhalides.

Abstract

Among the infrared (IR) optical material systems, the heavy-metal oxyhalide system has become an emerging system in recent years. Introducing heavy-metal cations and halogen anions with large atomic numbers is conducive to widening the IR transparency window and improving the birefringence value. Our experiments focus on the PbO-PbI<sub>2</sub> system and find a new lead oxyhalide, Pb<sub>4</sub>O<sub>3</sub>I<sub>2</sub>. The structure of Pb<sub>4</sub>O<sub>3</sub>I<sub>2</sub> is mainly composed of [OPb<sub>4</sub>] basic structure units, and triple-row [OPb<sub>4</sub>] units further connect to form unprecedented <sup>1</sup><sub>∞</sub>[O<sub>3</sub>Pb<sub>4</sub>] infinite chains. Pb<sub>4</sub>O<sub>3</sub>I<sub>2</sub> exhibits a wide IR transmission range from 0.49 to 15.0 μm, and theoretical calculation shows that Pb<sub>4</sub>O<sub>3</sub>I<sub>2</sub> has a large birefringence of Δ<i>n</i> = 0.098 @1064 nm. The results show that Pb<sub>4</sub>O<sub>3</sub>I<sub>2</sub> is an example of an IR optical material with good optical properties in heavy-metal oxyhalides, which significantly enriches the diversity of oxyhalides.
