TRANSPARENT ZNO NANOSTRUCTURE-BASED ULTRAVIOLET PHOTODECTORS AND FIRE MONITORING APPARATUS USING TRANSPARENT ZNO NANOSTRUCTURE-BASED ULTRAVIOLET PHOTODECTORS

摘要

PURPOSE: A transparent ultraviolet-ray sensor with a metal oxide nano structure and a fire-warning device applying the same are provided to selectively manufacture a metal oxide nano structure according to respectively desired functions by manufacturing a transparent ultraviolet-ray sensor and to recognize ultraviolet-rays of all directions. CONSTITUTION: A transparent ultraviolet-ray sensor with a metal oxide nano structure(300) comprises a transparent substrate(100), an insulating film layer(200), and an electrode. The insulating layer is formed on the transparent substrate. A metal oxide nano structure is composed of a metal oxide material on the insulating film layer. The electrode is formed in the top of the metal oxide nano structure. The transparent substrate is formed into a lower electrode. The electrode formed on the top of the metal oxide nano structure is formed into an upper electrode. [Reference numerals] (100) 400b(Lower electrode)
