Photoluminescence (PL) emission and excitation spectra and UV-visible absorption spectrum have been investigated in this paper. PL emission spectrum shows a wide emission band located at the range 350 nm-450 nm along with emerging of a sharp intense band at 376 nm. Normally, a broad emission band is observed in the bulk (micro/single crystal) material of LiF:Mg,Cu,P which is due to Cu+ transition. The nanorods have sizes approximately 50 nm in diameter and several hundreds nm in length. The sharp band at 376 nm may be attributed to quantum confinement. Moreover, the result obtained from the UV-visible absorption measurement is consistent with the PL result. It shows a broad absorption band contains a small sharp one at around 373 nm. These remarkable results might be useful for some applications such as high power lasers.  ISSN : 1752-8933  Journal Name : International Journal of Nano and Biomaterials  Volume : 2  Issue Number : 1  Publishing Year : 1430 AH 2009 AD  Article Type : Article  Added Date : Wednesday, December 21, 2011  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email نعمان صلاح Salah, Numan Researcher Doctorate nsalah@kau.edu.sa سامي حبيب Habib, Sami Researcher Doctorate sami_habib@hotmail.com ذيشان حسين خان Khan, Zishan H Researcher Doctorate zishan_hk@yahoo.co.in أحمد عبدالله الغامدي Al-Ghamdi, Ahmad A Researcher Doctorate AGAMDI@kau.edu.sa Files File Name Type Description  31709.pdf pdf Abstract Back To Researches Page
