Foreword

This standard replaces GB/T 14633-2002 "light rare earth trichromatic phosphors." This standard compared with GB/T 14633-2002, the main changes are as follows. --- Normative references added reference standard GB/T 5838 "phosphor terminology" and GB/T 20170.1 "rare earth metal Genera and rare earth compound particle size distribution measuring physical properties of the compound testing methods "; --- Delete "particle size distribution," "correlated color temperature" is defined; increase the "thermal quenching" of the definition; "heat stability" in the relative brightness and color Symbol coordinates expressed adjusted; --- The central value of the red phosphor chromaticity coordinates (xm, ym), the central value of a blue phosphor chromaticity coordinates (ym) and the original table 1, Table 2, Table 3, Table 4, particle properties (including center particle size, specific surface area) of the assessment by the assessment center value and deviation value adjustment Only deviation assessment for the whole, the center value is determined by supply and demand sides negotiated; --- Delete 1, Table 2 and Table 3, the assessment of the particle size distribution of the original table; --- Delete the original Tables 1 and 2 in the examination of thermal stability, thermal stability of the original table 3 of the assessment by the temperature adjusted to 550 ℃ 600 ℃; --- Merge former Table 1, Table 2 and Table 3. --- All grades increase the thermal quenching properties, pH, conductivity and assessment indicators; --- Delete the original table relative brightness, correlated color temperature assessment four pairs; deviation indicators and chromaticity coordinates of CRI has been adjusted.

1 Scope

This standard specifies the light rare earth trichromatic phosphor requirements, test methods, inspection rules and signs, packaging, transportation and storage. This standard applies to the high temperature reaction of the europium-activated yttrium oxide to terbium, cerium-activated magnesium aluminate, europium at low (or low-cost europium, Manganese) barium magnesium aluminate activated at 253.7nm UV excitation emit red, green and blue fluorescent phosphors, and by the Three kinds of phosphors are mixed by a certain percentage of light rare earth trichromatic phosphors. The main body used for low pressure mercury vapor fluorescent lamps.

3 Terms

GB/T 5838 and established the following terms and definitions apply to this standard. 3.1 Standard phosphor standardphosphors And certain requirements specified grades obtained, and after the performance calibrated for measuring the relative performance of the phosphor. Note. This standard uses the corresponding light rare earth trichromatic phosphors national standard sample as a standard phosphor. 3.2 Emission peak emissiondominantpeak Emission spectrum intensity of the largest peak. Unit nm. 3.3 The specific surface area specificsurfacearea Particle surface area to its mass (or volume) ratio. Units of square centimeters per gram (cm2/g) or square centimeters per cubic centimeter (Cm2/cm3). 3.4 Thermal stability thermostability Device fabrication process, the phosphor is heat-treated for stability. Note. This standard contains the relative brightness of thermal stability (ΔBh) and chromaticity coordinates of the thermal stability (Δxh, Δyh). 3.5 Thermal quenching (temperature quenching) temperaturequenching Luminescent properties caused by the temperature rise becomes weak/of the phenomenon when the temperature returns luminescent properties along with recovery.
