Random lasing in solution-processed perovskite thin films

Lead-Free Perovskites for Lighting and Lasing Applications: A Minireview

“…The main burst in this scientific area of utilizing the perovskite materials in lightning and lasing applications was caused by the synthesis of highly luminescent perovskite materials with QY above 80% [61,87]. At the present moment, the lasing perovskite materials possess wide range of morphology, including thin films [82,84,88,89,90,91,92], microstructures such as cubes [83,93,94,95,96,97], plates [81,98,99,100], wires [99,101,102,103,104], spheres [85,95,105], pyramids [97], nanosheets [106,107], microdisks [108,109], and quantum confined materials such as 2D R-P [110,111,112,113] and NCs [114,115,116,117], including NCs in glasses [118] and polymers [119]. Also, for the enhancement of the device performance, the perovskite materials can be patterned by ion beam lithography [109], laser ablation [108], or imprinting methods [89,120], and can be applied on the initially patterned substrates [81,90].…”

“…The electrical type of pumping [122] is not so widely used, however, is still perspective. As in the case of conventional lasers, perovskite-based lasers are also formed with resonators such as DBR or waveguide [82,89,90,91,110,113,114,119,120] and F-P [94,97,101,102,103,104,114,123] (Figure 6), and WGM [57,85,93,95,96,99,100,105,106,107,108,109,115,124] and RL [84,88,92,111,112,116,117,118] (Figure 7).…”
