Spin optoelectronics is an indispensable key for the future development of spintronics. Traditionally, spintronics relies on external magnetic fields and ferromagnetic contacts to achieve spin-polarized carriers. This makes it challenging to realize spin optoelectronic devices due to the inherently bulky and rigid constituent materials. To circumvent the existing shortcomings, we proposed an alternative approach and achieved spin optoelectronic devices using Chiral-MOF. Chiral-MOFs employed as a spin-injection layer via the chiral-induced spin selectivity (CISS) mechanism can effectively polarize the emitting light. This approach enables circularly polarized luminescence (CPL), which is free from external magnetic fields or ferromagnetic contacts. The obtained result offers a promising alternative in the field of spin optoelectronics and builds up an additional manner to manipulate the physical properties of spin-polarized optoelectronic devices.
