“…Additionally, ZnO possesses excellent transparency, intense luminescence at room temperature, low cost, non-toxicity, and remarkable chemical stability. These properties make it a versatile material with a wide range of applications in diverse fields such as photocatalysis [2][3][4][5], solar cells [5][6][7], gas sensing [8][9][10], radiation detection [11,12], radiation shielding [13,14], LEDs [15,16], and photosensors [17,18]. To tailor the properties of ZnO for specific applications, its structure is modified through ion activation from different groups.…”

Zinc oxide (ZnO) nanoparticles were synthesized hydrothermally using zinc acetate dihydrate and sodium thiosulfate pentahydrate precursors. The synthesized powders were sintered in air at 600 °C for different durations with a Cl-doping concentration of 25 mg/g. The optimal sintering time was found to be 5 h, resulting in the successful formation of the ZnO phase with small particle sizes of around 90 nm, nominal atomic fractions of Zn and O (~50%, ~50%), and increased luminescence intensity. The ideal concentration of Cl was discovered to be 25 mg/g of ZnO, which resulted in the highest luminescence intensity. The ZnO luminescence characteristics were observed in emission bands peaking at approximately 503 nm attributed to the transition from oxygen vacancies. A considerable improvement in the emission intensity was observed with increased Cl doping concentration, up to eight orders of magnitude, compared to pristine ZnO nanoparticles. However, the luminescence intensity decreased in samples with higher concentrations of Cl doping due to concentration quenching. These preliminary outcomes suggest that Cl-doped ZnO nanoparticles could be used for radiation detector development for radon monitoring and other related applications.
