Abstract

Material luminisensi ZnO (Zinc Oxide) telah disintesis menggunakan metode solution phase. Proses kalsinasi dilakukan pada temperatur 800°C. Penambahan doping dilakukan dengan menggunakan variasi konsentrasi doping 1%, 3%, dan 5% dengan temperatur kalsinasi 300°C untuk mendapatkan ZnO:Zn. Dilakukan identifikasi fasa dan karakterisasi optik untuk ketiga sampel yang dihasilkan. Intensitas luminisensi diuji untuk mengetahui pengaruh penambahan konsentrasi doping terhadap emisi yang diihasilkan oleh material luminisensi ZnO:Zn. Diperoleh hasil material luminisensi yang memancarkan emisi hijau dengan rentang panjang gelombang 510nm hingga 535nm. Semakin tinggi konsentrasi doping akan semakin banyak aktifator (doping) dalam host (ZnO) yang menyerap energi untuk proses eksitasi sehingga semakin tinggi pula intensitas emisi yang dipancarkan. ========================================================================================================= Luminescent material ZnO (Zinc Oxide) has been synthesized using solution phase method. The calcination process was performed at 8000C. The addition of doping was done by using variation of the 1%, 3%, and 5% doping concentration then were performed at 3000C to obtain ZnO:Zn. The phase identification and optical properties were characterized for all samples. Luminescent intensity were characterized to determine the effect of doping concentration on the emission of ZnO:Zn. Green luminescence was obtained in the range of 510nm to 535nm. The higher concentration of doping indicates more activators (doping) in the host (ZnO) which absorb the excitation energy so that the higher emission intensity emitted.
