A process for coating a phosphor of formula I: A[MF]:Mnincludes combining the phosphor of formula I in particulate form with a first solution including a compound of formula II: A[MF] to form a suspension and combining a second solution with the suspension, the second solution including a precursor including an element selected from the group consisting of calcium, strontium, magnesium, yittrium, barium, scandium, lanthanum, and combinations thereof. A population of particles having a core including a phosphor of formula I and a manganese-free composite coating disposed on the core, and a lighting apparatus () including the population of particles are also presented.

Coated red line emitting phosphors

A method and an apparatus for detecting photons are disclosed. The apparatus includes a scintillator single crystal and an avalanche photodiode coupled to the scintillator single crystal. The scintillator single crystal is at a temperature greater than about 175&#xb0; C. and at a shock level in a range from about 20 Grms to about 30 Grms. The scintillator single crystal includes a praseodymium doped composition selected from (LaY)2SiO:Pr, ABClX:Pr, A(Li,Na)LaClX:Pr, or any combinations thereof. As used herein A is cesium, rubidium, potassium, sodium, or a combination thereof, B is calcium, barium, strontium, magnesium, cadmium, zinc, or a combination thereof, and X is bromine, iodine, or a combination thereof. Further, (0&#x3c;x&#x3c;1), and (0&#x3c;y&#x3c;3).
