    Abstract: Provided are a polycrystalline phosphor film applicable to a high-power optical device, a preparation method therefor, and a vehicle lamp device using the same, wherein the polycrystalline phosphor film comprises a plurality of phosphor crystals and pores formed between the phosphor crystals, and the phosphor crystal can be a synthesized product comprising at least one rare earth material and cerium (Ce). In addition, the method for preparing a polycrystalline phosphor film can comprise the steps of: preparing a phosphor powder comprising a plurality of phosphor particles; injecting the phosphor powder into a predetermined mold so as to mold the same into a predetermined shape; generating a sintered body by primarily sintering, at a first temperature, the phosphor powder having the predetermined shape; secondarily sintering the sintered body, having been primarily sintered, at a second temperature lower than the first temperature; and forming a polycrystalline phosphor film by processing the sintered body having been secondarily sintered.

    Abstract: The present invention comprises the steps of: applying, on a substrate, a conductive paste including metal particles that are dispersed in an organic material and have a first particle diameter, and a magnetic heating element that has a second particle diameter; and selectively sintering the applied conductive paste by induction heating to form a conductive film, wherein the magnetic heating element may be contained in an amount of 10-50 wt% with respect to the metal particles. Therefore, a conductive adhesive layer can be selectively formed by performing the sintering through induction heating. In addition, by adding a small amount of the magnetic heating element to conductive metal powder having a low melting point, low-temperature bonding and electric conductivity can be simultaneously attained.
