Abstract

The invention discloses fluorescent powder with lighting color controlled by a preparation method and application of the fluorescent powder. The chemical formula of the fluorescent powder is Ca1-x-y-zSrxbayPrz)2Nb207, wherein 0<x<=0.03, 0<y<=0.03, 0.001<=z<=0.0075. The fluorescent powder prepared by the solid-phase synthesis method can emit red light as triggered by ultraviolet light, and the same-component fluorescent powder prepared by the sol-gel method can emit blue light as trigger by ultraviolet light. The same-component fluorescent powder prepared by the two method is mixed proportionally, emitted light can be continuously adjusted from red light to white light to blue light, and the fluorescent powder can be widely applied to the fields of lighting and display.

Description

technical field [0001] The invention relates to a fluorescent powder whose luminescent color is controlled by a preparation method and an application thereof, belonging to the technical field of inorganic luminescent materials. Background technique [0002] In recent years, with the advent of blue (450-470nm), near-ultraviolet (380-410nm) and deep-ultraviolet (190-315nm) light-emitting diodes (LEDs), there have been blue, near-ultraviolet and deep-ultraviolet LED chips and Light conversion phosphors are combined to make phosphor conversion LEDs that can emit light of various colors. Compared with traditional incandescent lamps, fluorescent lamps and high-pressure mercury lamps, this new type of solid light source has many advantages such as energy saving, high efficiency, environmental protection, long life (more than 10,000 hours), small size, etc., and has huge applications in the field of lighting and display. Prospects, it is expected to realize industrialization, repla...
