This invention discloses a color-tunable room-temperature phosphorescent carbon dot composite material based on minoxidil, its preparation method, and its applications. The composite material is synthesized in situ through a one-step thermal treatment of the clinical drug minoxidil (MND) and boric acid (BA) in an aqueous phase. Minoxidil, as a carboxyl-free aminopyrimidine molecule, partially forms nitrogen-doped carbon dots during pyrolysis, while some exist in an incompletely carbonized molecular state. Both are firmly anchored in a BA-derived rigid borosilicate glass matrix via B–N covalent bonds, effectively suppressing nonradiative transitions of triplet excitons. By controlling the doping amount of minoxidil (preferably an MND:BA mass ratio of 1:60 to 1:3), the phosphorescent emission color of the material can be continuously tunable from blue to green, achieving a maximum photoluminescence quantum yield of 20.9% and a room-temperature phosphorescent lifetime of up to 1.43 seconds. This composite material has significant application value in fields such as multi-level dynamic information encryption, time-resolved anti-counterfeiting, and intelligent optical devices.

The present invention provides a dry water absorption balance control method for low-temperature heat recovery of acid production from flue gas in a copper smelting converter, which belongs to the technical field of acid production from flue gas. It solves the technical problems of unstable acid concentration caused by fluctuations in flue gas concentration and water content after the introduction of a low-temperature waste heat recovery system of sulfuric acid in the existing flue gas acid production, and corrosion of pipelines and equipment by acid concentration. The present invention includes a drying tower, a degassing tower and a secondary absorption tower. After the drying tower absorbs moisture in the flue gas, low-concentration dry acid enters the circulating acid tank of the drying tower from the bottom of the drying tower to adjust the concentration, and then enters the secondary absorption tower through the degassing tower in sequence. In the present invention, the acid concentration control of the entire system is achieved by monitoring the acid concentration of each circulating acid tank in series, which can cope with the influence of flue gas concentration and water content fluctuations on acid concentration. On the premise of ensuring dry water absorption balance, the acid concentration is maintained to meet the design requirements, and the corrosion of pipelines and equipment by low acid concentration is effectively avoided, so as to achieve long-term safe operation of the dry absorption system with low-temperature waste heat recovery under the copper smelting converter process.
