Рассмотрены особенности люминофора LaCePO4, легированного Sm3+, для применения в дисплеях. Образцы, изготовленные традиционным модифицированным методом твердотельного синтеза, исследованы методами рентгеновской дифракции и ИК-Фурье-спектроскопии. Для более подробного изучения морфологии приготовленных образцов использована сканирующая электронная микроскопия. Представлен анализ фотолюминесценции (ФЛ) образцов люминофоров для разных концентраций легирующих ионов с возбуждением различных длин волн. В присутствии Sm3+ LaCePO4 излучает мощное синее и оранжевое свечение. Распределение спектральной области, оцененное по спектрам ФЛ, в координатах цветности Международной комиссии по освещению (x,y) 1931 г. располагается (0.20,0.22) в синей области. Полученный люминофор может найти применение в устройствах отображения.

We discuss new features of Sm3+ doped LaCePO4 phosphor as a potential candidate for display applications. Mainly, the traditional modified solid-state synthesis technique was used to prepare the samples. The X-ray diffraction technique was used for the structural studies. LaCePO4:Sm3+ phosphor production was verified by Fourier transform infrared studies. It was customary to use scanning electron microscopy to learn more about the morphology of the prepared samples. Additionally, photoluminescence (PL) analysis of the phosphor samples was presented for different doping ion concentrations with various excitations. In the presence of Sm3+, LaCePO4 emits powerful blue and orange emissions. In-depth research was carried out on the transitions between the concentration quenching effect and the doping ion. The distribution of the spectral region estimated from PL emission spectra was shown in the 1931 Commission International de l'Éclairage (x,y) chromaticity coordinates and was located (0.20,0.22) in the blue region. According to our research, as-prepared phosphor may find useful application in display devices, especially because of its blue and orange content.
