1 Scope

This standard specifies the relative light emission intensity of UV-emitting rare earth phosphors, emission peak and a half-width and determination of thermal stability. This standard applies to ultraviolet light emitting rare earth phosphors relative emission intensity, and the peak width at half maximum emission measurement and thermal stability.

3 Determination of the relative emission intensity

3.1 Principle of the method Sample emission peak in the ultraviolet band of 280nm ~ 380nm UV excitation at 253.7nm, the use of spectrum, corrected Quantity obtained in the sample relative 280nm ~ 480nm band emission spectrum, and then the same standard phosphor measured under the same conditions in 280nm ~ 480nm band emission spectrum of the integrated area of \u200b\u200bcomparison, the relative emission intensity light-emitting phosphors with rare earth UV. 3.2 Instruments and means 3.2.1 excitation of the sample, the measurement conditions 3.2.1.1 excitation test conditions. excitation (irradiation) light and the sample (or diffuse white) surface normal direction 45 °, to accept the direction perpendicular to the test Like surface (45/0); or excitation light perpendicular to the surface of the sample, and the sample surface to accept the direction normal to 45 ° (0/45); or using an integrating sphere Full Direction of the light acquisition mode. 3.2.1.2 Diffuse whiteboard requirements. measurement department calibrated repression AR BaSO4. 3.2.2 excitation light source UV emission 253.7nm, 253.7nm with a UV filter, the filter peak transmittance greater than 10% at 300nm ~ Transmittance within the wavelength range of 800nm \u200b\u200bis not more than 0.1%; 253.7nm radiation intensity stability better than 0.2%/10min, otherwise, should be added to compensate. 3.2.3 standard phosphor selection According to Table 1, selecting the sample to be tested corresponding standard phosphor. ......
