Peculiarities of formation and luminescence of ZnS nanoparticles modified with amino acids

A simple one-step synthesis of ZnS nanoparticles via salt-alkali-composited-mediated method and investigation on their comparative photocatalytic activity

“…Furthermore, three strong diffraction peaks are located at 2u values of 24.488, 47.428, and 56.308 corresponding to the (1 1 1), (2 2 0), and (3 1 1) diffraction planes of the cubic crystalline structure of as-synthesized ZnS nanoparticles, respectively. These values are close to those reported by Ehrlich et al[17]. The mean particle diameter D was estimated by using the Scherrer equation and via the most intense peak of the (1 1 1) plane of ZnS.…”

Фотолюминесценция ZnS : Cu в матрице полиметилметакрилата

“…В спектрах ПММА/ZnS наблюда-ется широкая полоса с максимумом в области 300 нм. Она отнесена к поглощению наночастиц ZnS [22]. После введения в состав композиций ионов меди в спектрах зарегистрирована сложная полоса в области длин волн λ = 280−(> 400) нм (см.…”

Chemical modification of the surface of highly dispersed metal salt crystals

“…Moreover, such an order of mixing allows one to retain many conditions of synthesis unvaried. This method has been success fully used, for example, for synthesis of nanoparticles of transition metal sulfides modified with amino acids [51][52][53][54] and LaF 3 nanoparticles modified with citric acid and glycine [55].…”
