In this paper, a random laser is fabricated based on carbon nitride particles as the scattering centers. We investigate experimentally the random lasing emission from the fabricated sample. Up to our knowledge, fabrication of random lasers based on carbon nitride particles has not yet been reported. We use rhodamine 6G solution as the gain medium. Optical gain is provided by rhodamine 6G solution via stimulated emission process. Essential optical feedback for random lasing emission is also provided by multiple light scattering from carbon nitride particles. Experimental results demonstrate the random lasing emission from the fabricated sample. We measure the threshold pump energy of the fabricated random laser and show that the presence of carbon nitride particles is essential for providing optical feedback and random lasing emission.
