INFRARED VISIBLE CONVERSION MEMBER AND INFRARED DETECTION DEVICE

Title:

INFRARED VISIBLE CONVERSION MEMBER AND INFRARED DETECTION DEVICE

Document Type and Number:

Japanese Patent JP2003083809

Kind Code:

A

Abstract:

To provide an inexpensive infrared visible conversion member and an infrared detection device having sufficiently high visible light generation intensity and resolution when converting an infrared ray into visible light.

This infrared visible conversion member 2a arranged on the light receiving surface of a photodetector 1 having sensitivity to visible light is characterized by adjusting a phosphor layer 3 including an up-conversion phosphor for converting the infrared ray into visible light so as to have the film thickness of 5-120 μm. Hereby, the visible light generation intensity and the resolution can be compatible with each other at a high level, and an image by visible light converted from the infrared ray is detected by the photodetector 1 with high sensitivity and high resolution, to thereby enable to realize an excellent infrared detection element.
