The night flying model airplane includes fuselage, wings and airscrew, and the fuselage and the wings are made of luminous material. The fuselage and the wings have in the surface adhered luminous paper with coated long-afterglow luminous agent. After being illuminated with natural light, lamp light, ultraviolet light, etc., the long-afterglow luminous agent can store the light energy and emit visible light in relatively high brightness after the illuminating light source disappears. The model airplane can emit light in night without needing battery to supply energy, and this makes the model airplane capable of flying for long time.

The invention discloses fluorescent powder for a white LED (light emitting diode) for illumination display as well as a preparation method and application thereof. The chemical general formula of the fluorescent powder is (Sr1-yCay)2-xSi5-zAlzN8-zOz:xEu<2+>. The preparation method comprises the following steps of weighing the raw materials according to the stoichiometric ratio of the chemical general formula and then weighing a cosolvent and an impurity removal reagent; carrying out mixing and grinding; and putting all the raw materials into a boron nitride crucible, carrying out high temperature heat preservation in a protective atmosphere, carrying out cooling to reach room temperature, grinding a sintered product and carrying out sieving so as to obtain the fluorescent powder for the white LED (light emitting diode) for illumination display. The fluorescent powder is used in various illumination display devices with near ultraviolet light as an excitation source. The fluorescent powder solves the problems that in the prior art, when a near-ultraviolet chip excites trichromatic fluorescent powder to form white light, reabsorption is caused, and the light conversion and energy conversion efficiency is low due to reabsorption, the light emitting uniformity is poor, and the color rendering property is poor due to the deficiency of red light. The fluorescent powder is suitable for the various illumination display devices with the near ultraviolet light as the excitation source.
