Transparent conducting films of CdSe(ZnS) core(shell) quantum dot xerogels

A method of fabricating sol–gel quantum dot (QD) films is demonstrated, and their optical, structural and electrical properties are evaluated. The CdSe(ZnS) xerogel films remain quantum confined, yet are highly conductive (10−3 S cm−1). This approach provides a pathway for the exploitation of QD gels in optoelectronic applications
