    Abstract: PURPOSE: Zinc galliumate useful as low voltage phosphor is manufactured by spraying mixed liquid of zinc nitrate and gallium nitrate by using an ultrasonic and heat-decomposing at 92000-1,200°C. CONSTITUTION: Zinc nitrate and gallium nitrate are melted in water in a ratio of Zn/Ga of 0.4-0.5 and added with 0.1-1 weight% of manganese nitrate, the mixed liquid is sprayed by using an ultrasonic oscillator(4). The sprayed mist is conveyed with carrier gas to a furnace and heat-decomposed at 92000-1,200°C. For example, 1.894g zinc nitrate and 5.155g gallium nitrate are melted in water in 100mL flask to give 100mL of 0.1M solution, which is poured into a receptacle with an ultrasonic oscillator. Oxygen is blown into the receptacle at 30sccm(standard cubic centimeters per minute, cm¬3/min). The temperature of furnace is raised to 1,100°C. A size of power particle shows a narrow distribution of 0.1-2 micro meter, a mean particle size is about 0.5 micro meter.
