Penumbuhan ZnO Rods Terdoping CeO2 Pada Substrat Kaca Menggunakan Metode Hidrotermal

Rina Dewi Mayasari

Abstract


Seng oksida (ZnO) rods murni dan terdoping serium oksida (CeO2) telah ditumbuhkan di atas substrat kaca dengan menggunakan metode hidrotermal. Penumbuhan ZnO rods memiliki dua tahapan proses utama, yaitu pelapisan seed (pembenihan) dan penumbuhan rods. Rasio konsentrasi Ce/ZnO adalah sebesar 1%, 5%, dan 10%. Efek dopan CeO2 pada struktur dan morfologi ZnO rods dianalisa dengan X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersion X-ray (EDX), dan Fourier transform infrared (FTIR). Spektrum XRD dari ZnO rods murni dan terdoping CeO2 memiliki fasa hexagonal wurtzite ZnO dengan tiga puncak tertinggi pada bidang kisi (100), (002), (101), serta fasa face-centered cubic CeO2 pada bidang kisi (111) dan (200). Hasil analisis SEM mengonfirmasi bahwa bentuk ZnO murni dan terdoping CeO2 adalah gumpalan hexagonal flower-like rods. Penambahan CeO2 telah menggeser puncak spektrum FTIR ZnO murni dari 729 cm-1 menjadi ~780 cm-1.
