Lamp powder generating ultraviolet rays B as well as preparation method and application thereof

Abstract

The invention belongs to the field of inorganic luminescent materials, and particularly relates to lamp powder generating ultraviolet rays B as well as a preparation method and application thereof. The lamp powder is alkaline-earth metal boron chloro aluminate, the lamp powder is applied to a lamp tube, under the excitation of 254 nm ultraviolet rays, the lamp powder can generate the ultraviolet rays B with the wavelength of 297 nm to illuminate the skin, so that subcutaneous 7-dehydrogenated cholesterol can be converted into vitamin D3, the metabolism of calcium and phosphorus of the human body can be promoted, and an effect for preventing children rickets and adult osteoporosis can be realized. In addition, the lamp powder does not contain harmful substances to the human body and is highin safety.

Description

technical field

[0001] The invention belongs to the field of inorganic luminescent materials, and in particular relates to a lamp powder for producing medium-wave ultraviolet rays and a preparation method and application thereof. Background technique

[0002] It is well known that 7-dehydrocholesterol in the human body can be converted into vitamin D under the irradiation of medium-wave ultraviolet rays. 3 , can promote the metabolism of calcium and phosphorus in the human body, and calcify the bone matrix. In the prior art, general lighting fluorescent lamps (fluorescent lamps) have no fluorescent powder that can emit medium-wave ultraviolet rays in the tube wall, and the tube wall coating of fluorescent lamp tubes for health care purposes already has calcium phosphate zinc thallium (Ca 0.94 Zn 0.06 ) 3 TL 0.03 (PO 4 ) 2 (Chinese Patent No. 96116266.X), or gadolinium-activated phosphate (Ca.12n.Gd) 3 (PO 4 ) 2.14 (Chinese Patent No. 022465014), used to emit medium-...
