Flexible polymer composite films incorporated with Li-ion/reduced ...
2019年10月29日 · A flexible polymer composite film (PL-rGO) was prepared from reduced graphene oxide (rGO) (derived from graphite) and lithium phosphate (Li 3 PO 4) incorporated in a pale yellow colored polystyrene sulfonic acid (PSSA) polymer by solution casting method.
Versatile photoluminescence from graphene and its derivatives
2015年7月1日 · Reduced graphene oxide (rGO) PL is somewhat different from GO because the number and size of sp 2 fragments are increased in rGO due to the elimination of the functional groups containing oxygen via reduction. Nanosized graphene/GO possesses a strong quantum confinement effect and hence emits intense excitation wavelength-dependent PL.
