ABSTRACT
A nano-Mn3B7O13Cl crystal was synthesized by a sol–gel method, and the structure, morphology and size were characterized by X-ray diffraction, scanning electron microscopy (SEM) and transmission electron microscopy. Effects of gamma radiation on the microstructure, luminescence properties, and medical performance for Mn3B7O13Cl have been discussed. The results show that Mn3B7O13Cl nanocrystals are uniform, and the average crystal size is about 50 nm. Under the 202 Gy measurement of gamma-ray irradiation, there are a large number of crystal defects in a chambersite crystal, and the defect is given priority with point defects and dislocations especially in gamma-ray irradiation with high energy. The luminescence intensity of natural chambersite in red light wavelengths increased obviously, and the luminescence intensity increased by 3.5 times. Nano-Mn3B7O13Cl exhibited the most significant antitumor activity and antiseptic effects. The best inhibition concentration of natural chambersite to A549 is 100 µg/ml, and its inhibition rate reaches 80%. Addition of natural chambersite in the solution significantly lowers the concentrations of Escherichia coli BL21, and the value is reduced by 97.6%. Therefore, chambersite has important application in the field of medical and shielding materials.
