Description
Summary:•We successfully synthesized the CsPb1−xMnxCl3 perovskite NCs with a Mn contents.•Perovskite film showed good water stability when immersed in water.•The luminous efficacy showed 16.2lm/W under a forward-bias current of 20mA. In this work, we first report a fabrication approach for CsPb1−xMnxCl3 perovskite film to address stability issues and for application in an optoelectronic device. The CsPb0.77Mn0.23Cl3 perovskite film is applied to a UV LED chip and the conversion efficiency is shown to be 16.2lm/W at less than 20mA. The CsPb0.77Mn0.23Cl3 perovskite film could be utilized as a new application for white LEDs, expanding the range of optical properties of LEDs, which could then be produced with reduced lead content.
