Specifically, the present invention provides a luminescent material comprising semiconductor nanoparticles having a mean particle size of 2 to 12 nm and a band gap of 3.8 eV or less, each of the semiconductor nanoparticles being coated with a silicon-containing layer, the semiconductor nanoparticles in the luminescent material having a peak emission wavelength 20 nm or more towards the longer-wavelength side than the peak emission wavelength of the semiconductor nanoparticles alone.

摘要： A power supply device includes: a power factor correction circuit which includes a capacitor and which corrects a power factor of power; a DC-DC converter which includes a switching element and which steps up or down an output voltage of the power factor correction circuit; a control unit; and a voltage detection unit which detects a voltage of an input side of the power factor correction circuit. The control unit controls the switching element such that an output voltage of the DC-DC converter is gradually reduced when stopping an operation of the DC-DC converter in a normal state in which the voltage detection unit does not detect a voltage lower than a predetermined value. When the voltage detection unit detects a voltage lower than the predetermined value, the control unit immediately turns off the switching element to stop the operation of the DC-DC converter.
