By a modified sol-gel method, from ethanolic solutions, Zn1-xCoxO nanoparticles have_x000D_ been synthesized. The effect of cobalt content in the crystal structure, wide band gap,_x000D_ and luminescence of ZnO nanoparticles have been observed. The immediate qualitative_x000D_ effect was the greenish hue of the final product obtained, which was more intense as_x000D_ cobalt percentage increased. The optical absorbance analysis by UV-vis spectroscopy_x000D_ showed three characteristic bands assigned to cobalt ion, which indicates the effective_x000D_ incorporation of ion dopants in the crystal structure of the ZnO host. The excitonic_x000D_ nature of the nanoparticles was clearly detected. However, in general, a redshift of the_x000D_ energy band gap as the cobalt content increasing was observed. By Photoluminescence_x000D_ spectroscopy, at room temperature, two emission bands were eviden...

THIS STUDY WAS DEVELOPED WITH THE OBJECTIVE OF DETERMINING THE LEARNING IMPULSE IN PHYSICS AND CHEMISTRY BY USING CHATGPT VIRTUAL ASSISTANTS AND BLOOM'S TAXONOMY IN UNIVERSITY STUDENTS, THE METHODOLOGY WAS QUANTITATIVE AND A LIKERT SCALE QUESTIONNAIRE WAS APPLIED FOR DATA COLLECTION, WHICH WAS CARRIED OUT IN A PRIVATE UNIVERSITY IN PERU. THE SAMPLE CONSISTED OF 120 PHYSICS AND 130 CHEMISTRY STUDENTS. AS PART OF THE RESULTS, IT WAS FOUND THAT 94% OF THE PARTICIPANTS HAVE A POSITIVE OPINION TOWARDS THE USE OF THE CHAT GPT VIRTUAL ASSISTANTS, IN THE SAME ORDER IT WAS FOUND THAT 88.4% CONFIRMED THAT THEY WERE IN THE HIGH LEVEL, IN RELATION TO AN IMPROVEMENT ASSOCIATED WITH SCIENTIFIC COMMUNICATION, 87.6% WERE IN THE SAME POSITION IN THE CATEGORY ANALYZE DATA AND EVIDENCE AND WITH RESPECT TO CALCULATE, OBTAIN AND EVALUATE RESULTS, THIS REACHED 88.8% ON THE HIGHEST RUNG. FROM THE ABOVE, IT WAS...
