Fluorescent films based on PVDF doped with carbon dots for evaluation of UVA protection of sunscreens and fabrication of cool white LEDs.

ABSTRACT: The ultraviolet-A (UVA) radiation from sunlight that reaches the earth's surface can induce premature aging, immunosuppression, and skin cancer. Commercial sunscreen products offer limited information regarding protection against UVA light. Therefore, proposing new and practical alternatives to evaluate the UVA protection capacity of commercial sunscreens is highly imperative. This work presents a novel methodology for evaluating the quality of sunscreens using polyvinylidene fluoride (PVDF) based films doped with plant derived photoluminescent carbon dots (CDs). The bluish white light emitting (under UVA exposure) PVDF/CD films were used to evaluate the UVA protection capacity of 8 different commercial sunscreens. The evaluation of UVA protection is based on the fluorescence attenuation o
