WebMar 30, 2024 · The first cross-linking reaction was spontaneously initiated in the solution state during the purification process, forming an ultrathin Si-O-Si amorphous matrix on the surface of the perovskite NCs. The second cross-linking reaction was intentionally induced in the film state by exposing it to UV light. WebThat means that that particular term disappears from the rate equation. The overall order of the reaction is found by adding up the individual orders. For example, if the reaction is first order with respect to both A and B (a = 1 and b = 1), the overall order is 2. We call this an overall second order reaction.
