Abstract:
1. A method for raising the luminous efficiency of a field emissive luminescent material, comprising following steps: taking a luminescent glass as a body; forming a nonperiodic metal film having metal micro-nano structures on a surface of the luminescent glass body to prepare a luminescent glass element; irradiating a cathode ray to the luminescent glass element, wherein the cathode ray penetrates the metal film and excites the luminescent glass body to luminesce; wherein, a chemical general formula of the luminescent glass body is aM 2 O.bY 2 O 3 .cSiO 2 .dTb 2 O 3 , wherein M is an alkali metal, and a, b, c and d are molar fractions, ranges of which are respectively as follows: the range of a is 25˜60, the range of b is 0.01˜15, the range of c is 40˜70 and the range of d is 0.01˜15.
