Tóm tắt

Vật liệu cadmium oxide (CdO) doped Gd3+ với cấu trúc vi tinh thể cao đã được tổng hợp bằng cách nung nóng precursor thu được từ phản ứng sol-gel. Phản ứng được thực hiện với các nguyên liệu cadmium nitrate (Cd(NO3)2·4H2O), gadolinium oxide, và ethylene glycol (C2H6O2) mà không có chất phụ gia ở nhiệt độ 80°C trong 2 giờ. Gel thu được đã được nung ở 900°C với tốc độ gia nhiệt tăng dần 15°C/phút trong 12 giờ trong lò. Kết quả của quá trình nung, phần hữu cơ của gel đã được loại bỏ, và cấu trúc vi cadmium oxide doped Gd3+ đã được tạo ra. Hợp chất thu được từ kỹ thuật sol-gel có cấu trúc tinh thể lập phương ở quy mô vi. Nghiên cứu XRD cho thấy CdO doped Gd3+ thu được có pha lập phương. Ngoài ra, hình ảnh SEM cho thấy vật liệu thu được bao gồm các hạt với cấu trúc cụm. Thêm vào đó, phổ FT-IR đã được sử dụng để đặc trưng hóa các cấu trúc vi CdO doped Gd3+.
