PURPOSE: To obtain a crystal phosphor thin film of a low-loss highly oriented up-conversion phosphor, by using a thin film of a specified barium fluoride material deposited at a low temperature which is higher oriented, as an up- conversion waveguide. CONSTITUTION: On a substrate 10, a phosphor thin film 12 having a greater refractive index than the substrate 10 and highly oriented is provided. The phosphor thin film 12 is deposited on the substrate 10 from corresponding fluoride by electron evaporation or heat evaporation. The phosphor thin film 12 is selected from BaLn2 F8 and Ba1-x Lnx F2-x . In this case, Ln is Y, Yb, Ho, Er, Tm, Py, or combination thereof, and (x) has a range up to 27. The phosphor thin film on the substrate becomes a waveguide. When optically coupled with a pump source for radiation in an IR region, the up-conversion phosphor thin film waveguide converts this radiation into visible rays or UV radiation. |

PURPOSE: To provide the light source for up conversion with an adequate optical absorption energy band by using the energy of pumping light efficiently for up conversion by a light source which generates visible light or ultraviolet light having shorter wavelength than the pumping light by receiving the pumping light. CONSTITUTION: The method and device for up conversion uses crystal structure 2 which is irradiated with the pumping light and emits visible light or ultraviolet light having shorter wavelength than the pumping light, and the crystal structure 2 is represented as M(1- X) RXZ3 or M2(1- X) R2 XO2 S. Here, M is a rare earth element such as cerium, gadolinium, yttrium, and lanthanum, R an impurity such as neodymium, thullium, erbium, holmium, and samarium, X a value of 0.005 to 1.0, and Z halogen such as chlorine, bromine, and iodine. Once the pumping light is received, this crystal structure 2 emits the visible light or ultraviolet light by a direct or indirect two-stage up conversion process. An electronic recording device also uses the up conversion crystal structure to expose a photosensitive material by this method. |

PURPOSE: To realize a space optical modulator which has a short response time and a high resolution by accumulating a specific electron trap material on a substrate.
CONSTITUTION: The electron trap material is made of an alkaline earth metal sulfide doped with two rare earth impurities and is formed as a film 30 on a substrate 20. When this trap material 30 is irradiated with blue light, the material 30 is electrically charged and is activated and is excited to fall to the trap level. Infrared light of the excited band on the electron trap material side is absorbed by blue light and is modulated. Infrared light which pass an inactivated area of the material 30 is not absorbed and is detected by a proper method, and orange/red light emitted from the material 30 and modulated blue light are filtered by a filter, thus obtaining the space optical modulator where infrared light is modulated by blue light.
