Commentaar:


Variété MANGANAPATITE: OL et OC: jaune, orange ; Activators: Eu2+, Ce3+, Mn2+, Dy3+, Nd3+, Sm3+ and Sm2+; TR3+ are located in the high symmetry Ca(I) position (Gorobets, Marfunin, Waychunas). Large pics: Mn2+ 569 nm, Mn3+ 583nm (yellow band); Other activator: U: 467, 486, 505, 526, 550 nm (gaft); Blue and violet luminescent colors due to Ce3+ and Eu2+; pink, violet pink, yellow pink: Sm3+, Dy3+; yellow band due to Mn2+ (Marfunin)

The diversity of the luminescence in Apatite is created in part by:

- the ability of the apatite structure to incorporate transition metal, REE and anion impurity activators and co-activators, often in combination;

- the varying types of associations and formation conditions that promote luminescence activity; and

- the nature of the structure of the apatite host itself. This favorable and flexible host structure has not been lost to commercial enterprises, as apatites have long been used as synthetic phosphors in industrial and consumer products. (Apatite Luminescence, Glenn A. Waychunas, Reviews in Mineralogy and Geochemistry; January 2002; v. 48)

The luminescence spectrum of fluorapatite from Panasqueira, Portugal, is characterized by four emission bands 349 nm (bandwidth:,10 nm) (REE possibly Ce3+); 445 nm (40nm)(REE possibly Eu2+); 555 rm (100 nm)(Mn2+ + REE sensitization (co-activator/UV absorber) most probably Ce3+ and Eu2+); 701 nm (50 nm)(Unknown activator).

Synthetic fluorapatite doped with manganese-II and antimony-V formed the basis for the second generation of fluorescent tube phosphors referred to as halophosphors (before 1942, synthetic Mn-doped willemite was used). When irradiated with 253.7 nm mercury resonance radiation they fluoresced with broad emission which appeared within the range of acceptable whites. The antimony-V acted as the primary activator and produced a broad blue emission. Addition of manganese-II produced a second broad peak to appear at the red end of the emission spectrum at the expense of the antimony peak, excitation energy being transferred from the antimony to the manganese by a non radiative process and making the emitted light appear less blue and more pink. Replacement of some of the fluoride ions with chloride ions in the lattice caused a general shift of the emission bands to the longer wavelength red end of the spectrum. These alterations allowed phosphors for Warm White, White and Daylight tubes, (with corrected color temperatures of 2900, 4100 and 6500 K respectively), to be made. The amounts of the manganese and antimony activators vary between 0.05 and 0.5 mole percent. Sometimes some of the calcium was substituted with strontium giving narrower emission peaks.

Since about 1990 the third generation TriPhosphors, three separate red, blue and green phosphors activated with rare earth ions and mixed in proportions to produce the desired color, have largely replaced halophosphors.
