Fig. 3From: Structure and Optical Features of Micro/Nanosized Carbon Forms Prepared by Electrochemical ExfoliationThe luminescent images of the P1–P3 types of the samples. The horizontal size of the sample areas is 250 (a, b) and 25 μ (c–e). a–d The images demonstrate edge areas, while the e, f other images demonstrate interior of the samples. The green (a–c, e, f) and red (d) glass filters were applied under microscopic studyBack to article page
